22

Answer 1

Answer:

22

Step-by-step explanation:

We know that 1 miles = 5280 ft  and 1 hour = 3600 seconds

15 miles         5280 ft         1 hour

--------------- * ------------- *   --------------        =

1 hour               1 mile        3600 second

The units cancel leaving us ft/s

22 ft/s
