Question 879673: Car A leaves a certain point and travels at a constant speed of 60kmph. 2 hours later car B leaves from the same point to overtake A travelling at 100kmph. How long will it take B to overtake A? Answer by mananth(16946) (Show Source):
Difference in time= 02:00 => 2.00 hours
Car A will have covered 120.00 km when Car B starts
catch up distance= 120.00 km
catch up speed = 100 -60
catch up speed = 40 mph
Catchup time = catchup distance/catch up speed
catch up time= 3
catch up time= 3.00 hours
