Question

13 speed task cards at what point(s) did the object stop? distance (km) time (hours)

Explanation:

Step1: Recall speed - distance - time concept

In a distance - time graph, when the object stops, the distance does not change with time, so the graph is a horizontal line.

Step2: Identify horizontal line segments

The horizontal line segments in the graph are between points B and C and between points D and E.

Answer:

Points B - C and D - E
