Question 454558: a car enters a highway at point A and travels west at a constant speed of 55 MPH. One hour later, another car enters the highway at point A and travels west at a constant speed of 65 MPH. How long does it take the second car to overtake the first? Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! Car A 55 mph
Car B 65 mph
Difference in time=01:00 1
Car A will have covered 55 miles before Car B starts
catch up distance= 55 miles
catch up speed = 65 -55 mph
catch up speed = 10 mph
Catchup time = catchup distance/catch up speed
catch up time= 55 / 10
catch up time= 5.5 hours
