MPH Problem #2

Mr. P finds that it takes him 4 minutes 25 seconds to walk a quarter of a mile.
How fast did he walk (in mph to the nearest tenth)?

Solution to the Problem:

Mr. P averaged 3.4 mph.

If it took Mr. P 4 minutes 25 seconds to walk 1/4 mile, then it would take 17 minutes 40 seconds to walk one mile.

Divide 60 minutes by 17.6667 minutes to get 3.396 or 3.4 miles in one hour.
