Final answer:
The graph best represents the distance traveled at a constant pace (option D).
Step-by-step explanation:
The graph best represents the distance traveled at a constant pace (option D).
Looking at the graph, we can see that the distance traveled remains constant for a certain period of time, indicating that the object is moving at a constant pace.
For example, if we consider a jogger running at a constant pace, the distance covered by the jogger would remain the same for a specific time period, resulting in a flat line on the distance vs. time graph, similar to the graph shown.
