Speed can be shown on a graph of distance versus time. The graph below shows the distance Mr. Martin traveled on his skateboard and the amount of time it took him to travel that distance.

Time
What may have happened in the time period between 5 and 8 seconds?
A. His speed increased
B. He is jogging at a constant speed
C. He stopped moving
D. His speed increased
Based on the information given in the graph, it is not possible to determine what happened between 5 and 8 seconds. The graph only shows the distance Mr. Martin traveled, but it does not provide any information about his speed or whether he stopped. Therefore, none of the given options can be determined from the graph.
Just guess
Given that the distance is decreasing from 5 to 8 seconds (going from 2 to 0), it is possible to make a guess that Mr. Martin may have stopped moving or his speed decreased during this time period. Therefore, based on this assumption, the answer would be:
C. He stopped moving
