  1. D = RT (Distance = Rate x Time)
    50 = rate going
    T = time going
    50T = distance going

    45 = rate returning
    T + .5 = time returning (30/60 = .5h)
    45(T + .5) = distance returning

    Distances are equal
    50T = 45(T + .5)
    50T = 45T + 22.5
    5T = 22.5
    T = 4.5 h

    50T = distance going
    50(4.5) = 225 miles

    Answer as a decimal?
