Answer:
C. 11 1/9 minutes/mile
Step-by-step 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
