The cars A and B travel on a level road in the same direction at a speed of 90 kph and  100 kph respectively. B is 80 m. ahead of A when brakes are applied on B causing it to  decelerate at a rate of 2 m/sec2. In what time will A overtake B? How far will car B have traveled until he was overtaken by A? How far will car A have traveled until he overtakes B?
