The diagram above shows the road from A to B and then to C. Asmadi drives a car through A with a speed of 96 km/h. He presses the brake to slow down the car to a speed of 15 km/h at B with deceleration of 3.75 m/s². Then, he accelerates to reach the speed of 105 km/h and arrives at C in 10 seconds. Calculate (a) the time taken for the journey from A to B. (b) the acceleration, in m/s², of the car along the road B to C.
