Answer:
Description 1 matches C.
Description 2 matches A.
Description 3 matches D.
Description 4 matches B.
Explanation:
Description 1 matches C. From graph C, we can see that the distance remains constant at a particular value. Hence, the car is not traveling and hence it is stopped.
Description 2 matches A. Speed is determined by the gradient of a distance-time graph. A depicts a linear graph which tells us that the gradient is constant and hence the car is at constant speed. The fact that the distance is increasing shows that the car is moving forward.
Description 3 matches D. Graph of D becomes less steeper as time progresses. This tells us that the gradient of the graph is decreasing and hence the speed of the car is decreasing.
Description 4 matches B. Graph B shows distance being decreased. This tells us that the car is coming back.
