Question

Fig. 13.15 Distance-time graph for the motion of two cars
13. Which of the following distance-time graphs shows a truck moving with
speed which is not constant?
Distance
Distance
Time -
Time →
(ii)
(i)​

Answer 1

Answer:

Correct option is C

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.
