Distance-time graphs show distance on the vertical axis ... text{change in hours}}\) Average speed = \( \frac{8}{3} = 2 \frac{2}{3}\) miles per hour. Note: We must use the total change in distance ...

Gradient = 5 m/s. Speed = gradient of distance-time graph = 5 m/s. The speed of the object represented by the purple line in the graph is 5 m/s. Calculate the average speed of the object ...
