उत्तर

Explanation:

  • 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 a distance-time graph indicates that the truck is moving at a speed that is not constant.
