**Average Speed? How do I calculate??**

How do I calculate average speed on a position time graph? Velocity time graph?

Thanks

For a velocity vs time graph, you can simply do (Final velocity - initial velocity) / 2.

For the velocity time graph, how do I get the average speed for the entire set of data? It starts at the origin, then goes up to (120,25) for A, and then the final point is F which is (720, -140)

For a velocity vs time graph, you can simply do (Final velocity - initial velocity) / 2.

To find the displacement on a V(t) graph, you need to look at the area under the curve. In this case, you would get two triangles, one above and one below the t axis (assuming the lines connecting your points are straight). Subtract the area of the triangle under the t axis from the area of the triangle above the t axis, and divide this by total time traveled. You are subtracting area below from area above because the object is traveling with a negative velocity (backwards) in the region below the t axis.
