Answer:
Measure the area under the graph.
Step-by-step explanation:
To calculate the distance traveled by a car (or anything) using a velocity-time graph, just measure the area under the graph! This is super easy. :)
I will use the graph below as an example. If you needed to find the distance traveled from 4 seconds to 10 seconds, you would just find the area under those two points. The dark blue is the area we need to find the area of.
The area of a rectangle is a A = bh
A = bh
A = (6 s)(8 m/s)
A = 48 meters
If you wanted to find the area from 0 seconds to 4 seconds, you would find the area of the light blue triangle.
A = 1/2bh
A = 1/2(4 s)(8 m/s)
A = 16 meters
If you wanted to find the area from 0 seconds to 10 seconds, you would just add these two areas!
A1 + A2
48 meters + 16 meters = 64 meters
I really hope this helped! :)
