Police chases a driver. Originally, the police is 1 mile behind the driver. The speed of the police car is 90 mph, and the speed of the chased car is 85 mph. How long will it take for the police to catch up with the car?

Respuesta :

Answer

12 Minutes

Explanation:

Police car speed=90mph

Chased car Speed=85mph

90-85=5mph

in 1 hour the police car will be 4 miles ahead, you need only 1 mile so you subtract 48 minutes and the answer will be 12 minutes to gain one mile on the chased car.
