and acceleration = velocity change ÷ time. To find the distance travelled, look at the area under the graph. In the first 10 seconds this is the area of the triangle, ½ × 10 s × 40 m/s = 200 m.

The speed-time graph in the question below shows how the ... d) During which section of the journey did the bus have the greatest acceleration? e) Calculate the acceleration of the bus during ...
