The question as text
A train travels between two stations, A and B. The train starts from rest at A and accelerates at a constant rate for T s until it reaches a speed of 25 m s−1. It then travels at this constant speed before decelerating at a constant rate, coming to rest at B. The magnitude of the train’s deceleration is twice the magnitude of its acceleration. The total time taken for the journey is 180 s.
