A racing car, moving with constant acceleration along a straight stretch of track, passes a fixed marker A with speed of 72 km/h. Two seconds later it passes a second fixed marker B. Given that the distance AB is 45 meters, find the acceleration of the car.


A third marker C is situated near the end of this section of track. Given that the speed of the car as it passes C is 216 km/h, find the time taken by the car to travel from A to C.
