1 Model trains move along a track passing through two model stations. Students analyse the motion
of a train. They start a digital timer as the train starts to move. They record the time that it enters
Station A and the time it enters Station B.
Fy 1.1 shows the time on entering Station A and the time on entering Station B.

(b) A faster train takes 54s to travel from Station A to Station B. The distance between the stations
is 120m.
Calculate the average speed of this train.
