Probably depends on the size of the 'body'. Are we talking about a 5 year old child or a 350 pound overweight adult?

It depends on gas prices, and whether stops need to be made to let the dog go potty.

It also might be determined by the ambient temperature. One minute is too quick, I gotta believe that 90 seconds is closer.

I think it is about 60 seconds if I remember correctly.

Does it stop and ask for directions?

I'm sure red blood cells have GPS now. I'll guess 25 seconds unless the person is getting ready to have a stroke and the it is 5 seconds.

depends on your heart rate ...

This should be interesting. Some funny and thought provoking answers.
