3.The graph below shows the distance and time traveled by a remote-controlled car.

The graph is a distance-time graph where the distance traveled is directly proportional to time, as indicated by the straight line passing through the origin. This means the car is moving at a constant speed.

Which of the following is correct about the remote-controlled car?

2.The graph below represents the relationship between speed and time for a car moving in a straight line.

The image displays a speed versus time graph for an object moving in a straight line. The graph shows a straight line originating from the origin (0 m/s at 0 s) and extending to a speed of 30 m/s at 3.0 s. This linear, upward-sloping line indicates that the object is undergoing a constant, positive acceleration. The slope of the line, which represents acceleration on a speed-time graph, is uniform throughout the entire time interval, meaning the speed is increasing at a steady rate from rest.

What is the acceleration of the car?
