  • 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
