You can put this solution on YOUR website! A police car receives a radio call to catch a vehicle that is speeding down the highway at 70 mph. The police car, which is 14 miles behind the vehicle, drives after it at 98 mph. How long will it take the police car to overtake the vehicle? (Distance, rate, time)
The cop's approach rate is 98-70 or 28mph, and since 14 is half of 28,
he'll catch him in half an hour.
