Distance travelled is the same as the shaded area under the graph. The shape is a triangle with a height of 30 m/s and base of 10 s.

Area of a triangle=12 × base × height

12× 10 s × 30m/s

= 150 m

Average speed = initial velocity + final velocity

0 m/s + 30 m/s divided by 2 =15 m/s

Distance travelled=average speed × time          

     15 m/s × 10 s =150 m

• Distance travelled is the same as the shaded areas under the graph. This graph has two shaded areas: the pink rectangle and the orange triangle.

Area of a triangle

=12× base × height

=12 × 40 s × 8.0 m/s

= 160 m
