Need help with math problem

If I get behind a truck carrying a huge, wide load, with no room to get around it, traveling at 5 MPH, how long would it take me to go half a mile?

It used to be 6 minutes, but that was before cellphones. Now you're going to have to allow time for the police and wrecker service to show up for the wreck you caused while taking a selfie and texting about the traffic jam. ;)

I have a degree in math. And I promise no algebra is needed. In fact, no numbers even! And yes, you could build a single bed larger than the two beds. Just imagine, if you could, pushing the two rectangular beds next to one another, so that they share one side. Since you haven't changed the beds at all, they will still have the same area. Now, you see that you have two walls which are inside the bed, which are not needed, If you removed this wood, couldn't you use them to enlarge the beds? (yes, I know this might be an "l" shaped bed, but that is not important right now. It happens that the largest bed that you can make for a given amount of wood is a square bed. However, since your wood is already of different lengths, and you have a certain space in your yard that you are working with, you probably will want to build a rectangle in the easiest way. Just build the "fattest" rectangle you can using the wood you have. But you already knew all of this, right? It just takes a certain way of looking at things. And it is this way of thinking that is the essence of math. Yes, math allows us to calculate areas and draw graphs, and do algebra. But it is the way we THINK about things that is the essence of math, not merely the equations. So don't let memories of algebra class scare you off. Besides, one of my university math professors often said that he tried to figure out how to build a door for his barn using calculus, and it didn't work! (Well, of course, the math wasn't wrong, but somewhere he made a mistake, by making it too complicated.) But if you really want to know how much bigger you can make your beds then you may find this helpful: The perimeter is the total amount of wood you will use and is equal to the length of all four sides added together (or sum the width and length, then double the sum.) The area is the width times the length. And remember that one square foot is (12 inches by 12 inches), or 144 square inches. So to avoid confusion, stick with either inches or feet in your calulations. And WHY might you want to do this? Because a pencil is a lot easier to push around than a raised bed! And if you want to post back here, I would be glad to check any calculations. Good luck!

Looks like justaguy2 came through with the math better than I could. I did want to throw in a couple of thoughts, though. Hopefully you are taller than me, as I know from experience that I can't reach into the center of a five foot bed easily without squishing some of my outer crops. If you put a trellice along the long edge you will have real problems trying to reach the "back" rows. My other thought is that I have recently seen a suggestion that when you build a long bed it is a good idea to put a brace in the middle to keep the long sides from bowing out. If you go to the site I put in the links below and follow the instructions to see previous episodes (unfortunately I coldn't find an URL to go straight to the building raised beds episode)and look at the episode about building raised beds for where I found usefull information about building long raised beds. (I have only built (4X4) ones. Here is a link that might be useful: Gardenfork TV

Not sure I agree. Unfortunately we're really missing some critical information such as if or when it compounds or are you just talking simple interest? That'll make a difference. Don't know start and end dates and don't know due dates and other terms or if there's any other charges involved - presumably not. Also the way it sounds there's no payments made, so from the simplest standpoint it could accumulate as follows: Loan originates on 9/22/9 with monthly payments. 9/22/9: 10% divided by 12 months = 0.83333333333333% per month. First payment would be due the following month and interest would accrue then, not in September. 10/22/9: 453.58 x 0.83333333333333% = 3.78 (plus prior balance = 457.36) 11/22/9: 457.36 x 0.83333333333333% = 3.81 (461.17) 12/22/9: 461.17 x 0.83333333333333% = 3.84 (465.01) 1/22/10: 465.01 x 0.83333333333333% = 3.88 (468.89) 2/22/10: 468.89 x 0.83333333333333% = 3.91 (472.80) 3/22/10: 472.80 x 0.83333333333333% = 3.94 (476.74) 4/22/10: 476.74 x 0.83333333333333% = 3.97 (480.71) 5/22/10: 480.71 x 0.83333333333333% = 4.01 (484.72) From this, 484.72 would be the end balance with accumulated interest. Subtract the starting amount of 457.36 would equal $31.14 in interest and totaling the monthly interest double checks at $31.14. You put it as a "bill" so if the first due date was September 22, 2009, then it might shift things back a month and add another $4.04 to the interest equaling $35.19 in interest unless there's a credit for paying 2 days early, which I'd assume isn't the case. And if it's not paid on time, it could add another interest charge too, but I'm assuming that's also not the case. So, with the limited info, that's the best I can guess.

Because I'm an idiot and I should have been dividing our FEE from the 50,0000. Not the entire settlement. It slapped me upside the head when I was making dinner last night. LOL 20,000 / 162,975 = 12.27% All better this morning. *chuckles*

Its 6 minutes.

At 5mph, it takes 1/5 hour to go 1 mile; It takes half of that time to go 1/2 mile or 1/10 hr to do 1/2 mile. 1/10 hour is 6 minutes. There is a more elegant way to calculate this, but this is understandable.

The rigorous way:

1 hr/5mile x 0.5 mile = 0.1 hr

0.1 hr x 60 min/hr = 6 min

Obviously I am worse at maths than I thought.

No, I just realised I didn't read the question properly.

This is quite a good question to ask occupants of any car behind such a truck.

Speaking of road users, what is causing all the tailgating out there? It's just ridiculous. You go the speed limit and still they are up right close behind you, trying to kill everyone. Just one little mistake and all Hell will break loose.

tete_a_tete, what lane do you use? If you are in the far left lane you are in the lane which is strictly for faster traffic and for people to pass the slower ones. If you are in the fast lane doing the speed limit and traffic is passing you on the right (another no-no) or is tailgating you you are not keeping up with traffic you need to move to the right. Keeping up with traffic means you may need to speed in order to pass the cars to your right, then move over to the right lane and drop back to the speed limit.

Let those around you pass so it keeps traffic flowing. If he average speed of the cars in the fast/passing lane is the "keeping up with traffic" (a federal law) and you are going slower than that, you should definitely be in the right lane unless you are keeping up with the person in front of you at a safe distance. There is NO good reason to drive slowly in the fast lane at all, when traffic is clear to you then PLEASE pull over to the right! This is a law I think that needs to be on every test EVERY 3 years when renewing your license plate, although different states have different time limits when you have to renew, my photo will be good from when I was 35 until I am 65!

Bottom line, no one will tailgate you in the slow lane, but if you are going too slow in the fast lane people will get pissed.

Tete, please stay in the right lanes. I'm convinced a large part of our population doesn't realize it's not cool to poke along under the speed limit in the left lanes. It may be easier for (the collective) you, so you don't have to pay as much attention to the left side of your car, but it creates frustration to those behind you.

Cornsnake, I'm gunna ignore that crude remark.

What crude remark?

Cornsnake, the vehicle codes are state laws. I don't think there are federal rules.

Yes, 6 minutes. If you can't go around it, it will take 6 minutes to go 1/2 mile. I figured it by dividing 1 hour (60 minutes) by the 5 miles per and got 12 minutes for 1 mile and so 1/2 mile would be 6 minutes. Thanks for giving my brain something to do today!!
