Question

4 in a distance - time graph, what does a steeper part of the line mean?5 how do you find the speed in a curved graph?

Explanation:

In a distance - time graph, the slope of the line represents speed. A steeper slope means a greater change in distance over a given change in time. For a curved graph, the speed at a particular point is found by drawing a tangent to the curve at that point and then calculating the slope of the tangent.

Answer:

1. A steeper part of the line in a distance - time graph means a higher speed.
2. To find the speed in a curved graph, draw a tangent to the curve at the point of interest and calculate the slope of the tangent.
