  1. speed = 7.6 mph
    time = 3.5 hr
    distance = speed x time = 7.6 x 3.5 m/hr
    =26.6


    2. time = 15 min = 15/60 hr = .25 hr
    distance = 24 miles
    speed = distance/time
    speed = 96 mile/hr


    3. time = 10 min = 10/60 hr = 1/6 hr

    distance = 2.4 miles

    speed = distance / time = 14.4 m/hr
