What is a Distance - Time Graph?
A Distance Time graph shows a journey that a person or object takes. The axes show time and distance.
It can map a path from start to finish, showing how far they are away from the start at any point and how long the journey has taken altogether.
It can also be used to calculate the speed at different sections of the journey, and the average speed overall.
