Here's an interesting graph from a study just published in ... times 150-meter laps), comparing the effects of pacing by time versus distance. Each kid started by running the 750-meter distance ...

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 ...

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}}{\ ...
