Question 694682: A train leaves a station and travels east at 72 km/h. Three hours later a second train leaves on a parallel track and travels east at 120 km/h. When will it over take the first train? Answer by mananth(16946) (Show Source):
Difference in starting time => 3.00 hours
Train I will have covered 216.00 miles before Train II starts
catch up distance= 216.00 miles
catch up speed = 120 -72
catch up speed = 48 mph
Catchup time = catchup distance/catch up speed
catch up time= 4.5
catch up time= 4.50 hours
