Refer to the following information for the next six questions.

Using the same position-graph as in section two above, answer these questions regarding how far the cart traveled, its average speeds during each interval, and its displacement. Remember that while

- **velocity** is determined by calculating the slope of a position-time graph,

- **distance** is found by calculating comparing the cart's position (the graph's y-axis coordinate) at two times (the graph's x-axis coordinate). Distance is a scalar quantity that does not depend on the direction of travel, and its

- **average speed** during a time interval is defined as the total distance it traveled divided by the total time taken.
