The total distance traveled by the car can be calculated as 25 ms 120 s 30 ms 220 s 15 ms 300 s 14100 m. Drawing a distance-time graph is simple. Average speed 10 30 2 20 ms Distance average speed time Distance 20 20 400 m.
Distance rate x time.
D v x t where v is the velocity average speed t is the time and d is distance so you can read it as Distance Speed x Time. The steeper the slope of the graph the faster is the speed. The average speed can be used to find the distance travelled. Examples solutions and videos to help GCSE Maths students learn how to read distance-time graphs and speed-time graphs.
