In traveling a distance of 3.7 km between points A and D, a car is driven at 107 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 5.7 seconds between B and C to give the car a uniform deceleration, calculate t and the distance s between A and B.
