John and Caroline go out for a walk one day. This graph represents the distance they traveled over time. During what part of their walk are they not moving?

To determine when John and Caroline are not moving, look for sections of the graph where the distance remains constant over time. These flat sections indicate that their distance from the starting point does not change, meaning they are stationary during those intervals. If the graph shows a horizontal line at any point, that indicates they were not moving during that time.
