    Distance = velocity times time

    x = v t

    distance covered by 40mph

    x = 40 t

    distance covered by 60mph

    x = 60 ( t-3)

    at catch up both distance are equal

    40 t = 60 ( t-3)

    40t = 60t - 180

    -20 t = -180

    t = 9 hours

    distance = 40 (9)

    =360 miles
