Answer 1

C. 11 1/9 minutes/mile

Explanation:

All answers are rates of time per distance, so we need to divide the given time by the given distance.

(40 minutes) / (3 3/5 miles) =

= (40 minutes) / (18/5 miles)

= 40 minutes * 5/18 miles

= 200/18 minutes/mile

= 100/9 minutes/mile

= 11 1/9 minutes/mile
