    We know that time is distance over velocity, that is:

    time = distance / velocity

    t = d / v

    Now from the given:

    d / 460 + d / 500 = 4.8

    Now we can find for d:

    d = 4.8 / [1/460 + 1/500]

    d = 1150 miles

    So the time of each flight is:

    flight = 1150 / 460 = 2.5 hours

    return flight = 1150 / 500 = 2.3 hours
