In traveling a distance of 3.5 km between points A and D, a car is driven at 87 km/h from A to B for t seconds and 49 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 distance s between A and B. 87 km/h 49 km/h 3.5 km Answers: t = i 68.76 i 1.6617 km
