A distance-time ... line in the graph is 2 m/s. Calculate the average speed of the object represented by the purple line in the graph, from 0 to 2 s. Draw a right-angled triangle between the ...

The area under a speed-time graph represents the distance travelled. The object is accelerating at \(\frac{8}{4} = 2~m/s^2\). It travels \(\frac{1}{2} \times 4 \times 8 = 16~m\). Between 4 and 7 ...
