The graph which represents Charlies distance from her car at different times is indicated as attached. The schedule of her movement is also attached. This type of graph is called Distance Time Graph.
<h3>What is a distance-time graph?</h3>
A distance-time graph can show the distance traveled while an item moves in a straight line.
The gradient of the line in a distance-time graph is equal to the object's speed. The item is travelling more quickly the steeper the line and the larger the gradient.
See the attached for Charlies Distance - Time movements visualized in a graph.
