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 ...

Key fact The gradient of speed-time and velocity-time graphs represent acceleration. The area under a speed-time graph represents the distance travelled.

Distance traveled by car (s)= 200 km Time (t)= 3 hours Since the unit of speed is meter for distance and second for time, the distance and time have to be converted into meters and seconds ...
