Final answer:
The slope of a distance vs time graph represents speed.
Step-by-step explanation:
The slope of a distance vs time graph represents speed.
To understand this, we need to know that slope is the ratio of the change in the vertical direction (in this case, distance) to the change in the horizontal direction (in this case, time). So, the slope of a distance vs time graph gives us the rate of change of distance over time, which is also known as speed.
For example, if the slope of the graph is 2 units of distance per 1 unit of time, it means that the object is traveling at a speed of 2 units of distance per unit of time.
