Gradient = \(\frac{6}{3}\). Gradient = 2 m/s. The speed of the object represented by the green line in the graph is 2 m/s. Calculate the average speed of the object represented by the purple line ...

Save guides, add subjects and pick up where you left off with your BBC account. The speed is \( \frac {20}{10} = 2~m/s\). Key fact The gradient of a distance-time graph represents speed.
