In traveling a distance of 3.6 km between points A and D, a car is driven at 85 km/h from A to B for t seconds and 40 km/h from C to D also for t seconds. If the brakes are applied for 3.7 seconds between B and C to give the car a uniform deceleration, calculate t and the distances between A and B. Answers: t = 85 km/h S= i i B C 3.6 km 40 km/h S km D
