A student draws a distance-time graph fete moving scooter and finds that a section of the graph is a horizontal line parallel to the time axis. Which of the following conclusion is correct about this section of the graph?

Options

A. the scooter has uniform speed in this section
B. the distance travelled by scooter is the maximum in this section
C. the distance travelled by the scooter is the minimum in this section
D. the distance travelled by the scooter is zero in this section

Answer

To solve the question regarding the distance-time graph of a moving scooter, we need to analyze the information provided about the horizontal line section of the graph. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand the Distance-Time Graph
In a distance-time graph, the x-axis represents time, and the y-axis represents distance. The slope of the graph indicates the speed of the object.

**Hint:** Remember that a horizontal line in a distance-time graph indicates no change in distance over time.

### Step 2: Identify the Meaning of a Horizontal Line
A horizontal line parallel to the time axis means that the distance remains constant while time progresses. This implies that the object is not moving.

**Hint:** Think about what it means when an object is stationary. What happens to its distance over time?

### Step 3: Analyze the Options Given
1. **Uniform Speed**: This option suggests that the scooter is moving at a constant speed. This is incorrect because a horizontal line indicates no movement.

2. **Maximum Distance**: This option states that the distance traveled is maximum. This is also incorrect since the distance is constant and does not increase.

3. **Minimum Distance**: This option suggests that the distance traveled is minimum. While it may seem plausible, it is not the best choice since the distance is actually zero during that time.

4. **Zero Distance**: This option states that the distance traveled by the scooter is zero during that section of the graph. This is the correct conclusion because a horizontal line indicates that the scooter is not moving.

**Hint:** Evaluate each option based on the definition of a horizontal line in a distance-time graph.

### Step 4: Choose the Correct Conclusion
Based on the analysis, the correct conclusion is that the distance traveled by the scooter is zero during the section of the graph that is a horizontal line parallel to the time axis.

**Final Answer:** The correct conclusion is that the distance traveled by the scooter is zero in this section (Option 4).
