Question 1: Identify the total time taken for the object to reach its maximum distance from the start based on the graph.

Answer: 12 minutes

Question 2: Calculate the average speed of the object between 4 minutes and 10 minutes.

Answer: 3 km/h

Question 3: Describe the motion of the object between 6 minutes and 8 minutes based on the graph.

Answer: The object is stationary; the distance remains constant.

Question 4: Plot the graph of y=2x for x values from 0 to 6 on the grid.

Answer: Students will draw a straight line passing through (0,0) to (6,12).

Question 5: Construct a triangle with vertices at (2,4), (4,8), and (6,4).

Answer: Students draw the triangle on the grid, verifying side lengths and angles as needed.

Question 6: The graph shows a constant speed for the first 5 minutes, then a sudden stop. How can this be interpreted?

Answer: The object was moving at a steady speed, then came to rest.

Question 7: Calculate the distance covered during the first 3 minutes if the speed was 4 km/h.

Answer: 0.2 km

Question 8: Explain what a steep slope on a distance-time graph indicates about the object’s speed.

Answer: A steep slope indicates a high speed.

Question 9: Identify the section of the graph where the object is moving at a constant speed.

Answer: Between 0 and 5 minutes.

Question 10: A student claims that a flat section of a distance-time graph always indicates the object is stationary. Is this correct? Explain why or why not.

Answer: Yes, because a flat section shows no change in distance, indicating the object is not moving.

Question 11: Error analysis: A student draws a graph with an incorrectly scaled y-axis. How could this mistake affect the interpretation of the graph, and how can it be fixed?

Answer: Incorrect scaling can misrepresent speeds. Fix by ensuring the y-axis scale matches actual distances.
