Question

Which of the following distance-time graphs shows a truck moving with speed which is not constant?

Answer 1

Graph (iii)

In a distance-time graph, the constant speed of a truck will be represented by a straight line.

In a distance-time graph, a straight line parallel to the time axis indicates that the truck is not moving.

A curved line on the distance-time graph indicates that the truck is moving with a speed which is not constant.
