Distance Time Graph - GCSE Maths Definition

Reviewed by: Dan Finlay

Published

A Distance-Time Graph is a type of graph used to show how distance changes over time. On this graph, the horizontal axis (x-axis) represents time, while the vertical axis (y-axis) represents distance. When you look at the graph, you can see how far an object has travelled over a certain period.

If the line on the graph is straight and slopes upwards, it means the object is moving at a constant speed. If the line is horizontal, the object is not moving. A steeper line means the object is moving faster. Understanding Distance-Time Graphs helps you interpret how quickly something is travelling or if it is staying still.
