In traveling a distance of 4.5 km between points A and D, a car is driven at 119 km/h from A to B for t seconds and 53 km/h from C to D also for t seconds. If the brakes are applied for 3.9 seconds between B and C to give the car a uniform deceleration, calculate t and the distances between A and B. 119 km/h B 4.5 km 53 km/h D
