    22 miles per hour

    Step-by-step explanation:

    d = rt

    100 = 3.1r

    r = 32.26 ft/sec

    (convert seconds to minutes)

    x 60 seconds = 1935.48 feet per minute

    (Convert minutes to hour)

    X 60 = 116,129.02 feet per hour

    / 5280 = 21.99 miles per hour

    Rounding up figures ~ 22mph
