The slope of the distance-time graph at any point gives______.
The slope of the distance-time graph indicates the speed.
Assertion: The slope of the distance-time graph of a body moving with high speed is steeper than the slope of the distance-time graph of a body with low velocity.
Reason: Slope of distance-time graph = speed of the body.
