Like distance and time speed and time can be placed visually on a graph as well. The steeper the slope, the faster it is either accelerating or decelerating.
Acceleration is the change in speed over time.
Usually in a speed time graph, the equation of the slope is still the y axis over the x axis in which y represents the speed, and x represents the time.
The area under the line represents the total distance. Using mathematical formulas you can find the area under the line.
Once the slopes are divided into geometric shapes either usually, triangles or squares you can find the distance, you must know these formulas however.
Triangle: b x h / s
Square: b x h
Note: notice that distance, time, speed are all related to each other.
