A train travels between two stations along a straight track.
The Figure shows the velocity/time graph for the journey.

Describe the motion of the train between 40 s and 100 s.
Calculate the acceleration of the train in the first 40 s.
Explain how the graph shows that the deceleration of the train between 100 s and 125 s is greater than its acceleration in the first 40 s.
Determine the distance travelled by the train between 40 s and 100 s.
Determine the total distance travelled by the train between the two stations.
