Question 685928: you can travel 40 miles on motorcycle in the same time that it takes to travel 15 miles on bicycle. if your motorcycle's rate is 20 miles per hour faster than your bicycle's, fine the average rate for each Answer by lwsshak3(11628) (Show Source):
You can put this solution on YOUR website! you can travel 40 miles on motorcycle in the same time that it takes to travel 15 miles on bicycle. if your motorcycle's rate is 20 miles per hour faster than your bicycle's, fine the average rate for each
let x=rate of speed of bicycle
x+20=rate of speed of motorcycle
travel time= distance/rate of speed (same for both)
40/(x+20)=15/x
40x=15(x+20
40x=15x+300
25x=300
x=12
x+20=32
rate of speed of bicycle=12 mph
rate of speed of motorcycle=32 mph
