The answer is: C.
To determine which graph shows a car moving with constant speed, we need to look for a graph that represents a straight line. A straight line indicates that the car is covering the same distance over equal time intervals, indicating constant speed.
The correct answer is graph C.
To determine which graph shows a car moving with constant speed, we need to analyze the characteristics of each graph.
The key characteristic to look for in a graph depicting constant speed is the uniform spacing between each point on the graph. This indicates that the car is covering equal distances in equal intervals of time.
Now let's analyze each graph:
Graph A: The points on this graph are spaced unevenly. The spacing between points is wider at the beginning and narrower towards the end. This indicates that the car is not moving with a constant speed. Therefore, Graph A does not show a car moving with constant speed.
Graph B: The points on this graph are also spaced unevenly. The spacing between points is wider at the beginning and narrower towards the end, similar to Graph A. This indicates that the car is accelerating or decelerating, not moving with a constant speed. Therefore, Graph B does not show a car moving with constant speed.
Graph C: In this graph, the points are equidistant from each other, maintaining a uniform spacing. This indicates that the car is covering equal distances in equal intervals of time, suggesting it is moving with a constant speed. Therefore, Graph C shows a car moving with constant speed.
Graph D: Similar to Graph A and Graph B, the points on this graph are spaced unevenly. The spacing between points is wider at the beginning and narrower towards the end, indicating that the car is not moving with a constant speed. Therefore, Graph D does not show a car moving with constant speed.
Based on the analysis, the correct answer is Graph C.
