Distance travelled per unit of time.
Used by AQA, Edexcel and OCR
Specification R1, R11 · Paper 1, Paper 2, Paper 3
The distance travelled per unit of time, calculated using distance divided by time.
Revise: Unit ConversionsStops count as part of the total journey time unless the question specifically asks for speed while moving.
For a speed in km/h, use kilometres and hours before dividing, or convert a value in m/s by multiplying by 3.6.
For an average speed, use total distance divided by total time. Do not simply take the mean of the speeds for different stages.
Convert incompatible units before calculating. For example, convert minutes to hours if the required speed is in km/h.
