it takes 35 minutes for mr morrison to drive 25 miles to work. rounded to the nearest mile per hour, what is the speed in miles per hour?

  • math -

    D = RT (Distance = Rate x Time)
    R = D/T

    35 min = .58 hour (35/60)
    D = 25 mi, T = .58 h
    R = 25/.58 = 43.10 mph

    to nearest mph = 43 mph

  • math -

    25/35 = x/60

    35x = 1500
    x = 42.85 = 43
