Answer:
Step-by-step explanation:
On the return trip from the beach, you pedal hard for the first ten minutes and cover 4 miles.
Speed = distance covered/time taken
This means that your speed for the first 4 miles would be
4/10 = 0.4 miles per minute
Tired, you slow down and cover the last 6 miles in 36 minutes. This means that your speed for the last 6 miles would be
6/36 = 0.17 miles per minute
Therefore, your average speed for the return trip would be
(0.4 + 0.17)/2
= 0.285 miles per minute
