Question

Carlton ran 7 3/4 miles in 52 7/10 minutes. what is his average pace per mile?

Answer 1

The answer is 6.8 minutes per mile.

Explanation:

We change: 7 3/4 = 31/4

and 52 7/10 = 527/10

Then 31/4 miles in 527/10 minutes, that means 1 mile will be in (527/10)/(31/4).

So we calculate: (527/10)/(31/4)= (527/10)*(4/31) = (527*4)/(10*31)= 17*4/10 = 17*2/5 = 34/5= 6.8

The answer is 6.8 minutes per mile.

Hope you understand.
