First choose two points that lie the line - say point A is 0 0 and point B is 10 50. Calculating Speed from a Distance-Time Graph The average speed can be calculated for any part of a journey by taking the change in distance and dividing by the change in time for that part of the journey. Acceleration is change in velocity divided by time.
The slope of a speed-time graph is acceleration.
One way to represent the motion of an object is by using a speed vs. Examples solutions and videos to help GCSE Maths students learn how to read distance-time graphs and speed-time graphs. Speed Final Position-Initial positionTime. These are quite far apart so that will make our gradient calculation more accurate.
