Question

A police car accelerates quickly to 60 meters per second in order to pursue a minivan that is recklessly speeding along the highway at 45 meters per second. how long will it take the police car to catch up if the minivan is 600 meters ahead of the police car at the beginning of the chase?

Answer 1

1. You have that:
 -The police car accelerates 60 meters per second.
 - The minivan has a speed of 45 meters per second and is 600 meters ahead of the police car at the beginning of the chase.
 2. Therefore, you have:
 V1xt=V2xt-600
 V1 is the speed of the minivan and V2 is the speed of the police car
 3. The time is:
 t=-600/V1-V2
 t=-600/(45-60)
 t=40 seconds
