A tram travels 12 km from Station P to Station Q. It takes 20 minutes.
State the equation linking average speed, distance moved and time taken.
Calculate the average speed of the tram and state its unit.
The maximum speed of the tram must be higher than the average speed you calculated. Explain why.
The tram continues along a straight track from Station Q to Station R.
The graph shows how the velocity of the tram changes with time during this part of the journey.
Use the graph to calculate the acceleration of the tram, in m/s2\text{m/s}^2m/s2, during the first 60 seconds after it leaves Station Q.
Use the graph to calculate the distance, in m, between Station Q and Station R.
