Final answer:
The slope of a distance-versus-time graph represents the speed of the object.
Step-by-step explanation:
The slope of a distance-versus-time graph represents the speed of the object.
When you have a straight line on a distance-versus-time graph, the slope represents the rate at which the distance is changing over time, which is the object's speed. The steeper the slope, the faster the object is moving, and the shallower the slope, the slower the object is moving.
For example, if the slope of a distance-versus-time graph is 5 meters per second, it means that the object is moving at a speed of 5 meters per second.
