It will take 2 hours for the ambulance to pass the police car.

Given that a police car leaves a crime scene heading east directly towards the hospital at 72 kilometers per hour, and an ambulance leaves a quarter of an hour later and also heads directly east towards the hospital at 81 kilometers per hour, to determine how long will it take for the ambulance to pass the police car, the following calculation must be performed:

  • 72 x 0.25 = 18
  • 81 - 72 = 9
  • 18/9 = 2
  • 72 x 0.25 + 72 x 2 = 162
  • 81 x 2 = 162

Therefore, it will take 2 hours for the ambulance to pass the police car.
