1.1. A train travels at a constant speed of 45.0 m/s.

Calculate the distance it travels in 1.50 minutes.

Give your answer to 3 significant figures.

   Distance (3 significant figures) = .................... m

1.2. Calculate how long it takes (in minutes) for the same train travelling at the same speed to travel 10.0 km.

Give your answer to 3 significant figures.

   Time (3 significant figures) = .................... minutes

1.3. Higher Tier Only

A toy train is made based on the train in parts (a) and (b). The toy train is shown in Figure 1.

A toy sign is placed at the side of the track.

The toy train is powered by a battery and moves along a circular track.

Compare the speed of the train and the velocity of the train.

1.4. Higher Tier Only

The speed-time graph of the model train is shown in Figure 2.

The points at which the train passes the sign are indicated on the graph.

Calculate the circumference of the circular track.

Give your answer to 2 significant figures.

   Circumference (2 significant figures) = .................... m
