Question 476955: Car D is traveling at 60mph behind Car E, which is traveling at 50mph and is 15 miles ahead. How long will it take Car D to reach Car E? Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! Car E 50 mph
Car D 60 mph
Car E is ahead by 15 miles
catch up distance= 15 miles
catch up speed = 60 -50
catch up speed = 10 mph
Catchup time = catchup distance/catch up speed
catch up time= 15 / 10
catch up time= 1.5 hours
