A travel graph is sometimes also called the time graph.
A travel graph is a type of line graph representing a journey. It compares the distances travelled with times taken. In a travel graph:
- the time is shown in the horizontal axis
- the distance travelled is shown in the vertical axis
- the steepness of the line represents the speed of the object. The steeper the graph the greater the speed
- a horizontal line indicates the object is at rest or is stationery, i.e. it is not moving, and its speed is zero.
- we assume that the travel is along a straight road
- we use the formula speed = to find the value of time (or distance travelled) when speed is given.
