Answer:
The answer is 6.8 minutes per mile.
Step-by-step 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.
