Question 1005047: a speeding car is traveling at 80 mph when a police car starts pursuit at 100 mph. How long will it take the police car to catch up to the speeding car is the car is 2 miles ahead? Assume both are going at a constant speed. Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! Since their difference in speed is 20 mph, we want to know how fast the police car makes up the 2 mile head start...
Since d = rt, then
t = d/r = 2/20 = .1 hour = 6 minutes
