You can travel 40 miles on a motorcycle in the same time that it takes to travel 15 miles on a bicycle. If your motorcycle's rate is 20 miles per hour faster than your bicycle's rate, find the speed of the motorcycle and bicycle.

motorcycle = 32mph
bicycle = 12 mph

Are these correct?

    D=RT
    40=(20+B)T
    15=BT (15/T)=b

    40=(20+(15/T))T
    40/t=20+15/t
    25/t=20
    25=20t
    t= one and one fourth

    B=(15/(5/4))=12
    12+20=32

    B=12
    M=32
    You are correct
