His average speed for the return journey is 60km/h and he completes it in 3 hours less than it took him to reach his destination. How long did the forward journey take? Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! let him take x hours to go there
distance = 50x
return he takes x-3 hours
at 60 km/h
distance = (x-3)*60
distance is same
(x-3)*60=50x
60x-180=50x
10x=180
x=18 hours
