Question

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?

Answer 1

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

Answer 2

Thanks.
