18.2 Calculating Speed, Distance and Time In this section we extend the ideas of speed to calculating distances and times, using the following formulae: Speed = Distance Time Distance =Speed Time× Time = Distance Speed Example 1 Jane drives at an average speed of 45 mph on a journey of 135 miles. How long does the journey take? Solution Time ...

Speed from a distance-time graph For the red line, the object travels m in seconds. Hence, we can calculate its speed: m/s N.B. The steeper the line, the faster the speed. E.g. 1 Answer these questions based on the distance-time graph above. (a) How long is the object stationary for? (b) Calculate the speed indicated by the purple line.
