Horizontal Distance

06/30/2009 12:31 AM

Im in the military, the other day we were doing a PT test, which is suppose to be 2 miles. Our superior took his vehicle with a rim of 20" and who knows how large the tire was, it was a Mitsubishi SUV and drove 1 mile and marked it off, wrongly assuming he had measured accurately using his odometer but not taking into account the Rolling Radius of the vehicle. Now where the average male in our unit finishes the 2 miles in about 1500 mins, we got times of 9.5 mins. I tried to explain to him his error is there a formula or can i get assistance in why his theory was so obviously wrong.

"Now where the average male in our unit finishes the 2 miles in about 1500 mins",

I hope you are not in the military of the USA!

<...2 miles in about 1500 mins...>

A baby can crawl faster than that.

Hmmmm....

Assuming that your 1500 mins was a typo...

15 mins is the norm for 2 miles and the actual time for the run taken was 9.5 mins.

15/9.5 = 1.579 and there is 1.61 kilometers per mile

It might be a coincidence....but the maths fits a distance of 2 km or 1.25 miles based on previous timed runs.

Check the odometer units.
