Answer by mananth(16946) (Show Source): You can put this solution on YOUR website!
A to B x mph
B to A 15 mph slower
returning speed x-15
returning time = 5 hours
going out time= 3 hours

Distance = same
3 x = 5 ( x -15 )
3 x = 5 x 0 -75
3 x - 5 x = -75
-2 x =-75
/ -2
x=37.5 mph

Returning speed= 22.5 mph
