The speed is \( \frac {20}{10} = 2~m/s\). Key fact The gradient of a distance-time graph represents speed. When displaying a journey, the vertical axis will often represent the distance from a ...

Next, I can repeat this calculation for the other distance-time values and then average all of the accelerations. Isn't this the same thing as making a graph? Well, no. You might get a similar ...

Distance-time graphs show distance on the vertical axis and time on the horizontal axis. The gradient of a distance-time graph represents speed because gradient = \( \frac{\text{change in y} ...
