Answer:


12\:mph

Explanation:

Multiply the proportion [both denominator and numerator] by 3, since you have to multiply 20 by 3 to get one hour. Then, whatever is done to the bottom is also done to the top, so 3 by 4 is 12, therefore you have 12 mph.

I am joyous to assist you anytime.

20 minutes is 1/3 of an hour, so an hour can be split into 3 20 minute sections.

They run 4 miles each 20 minute section equals 4 x 3 = 12 miles per hour.
