What was the point of HW8?

Isn't average speed just the average (mean) of the inital speed and the final speed?

What's the average speed of this graph (from 0 secs to 20 secs)?

Using the average of the initial speed and the final speed only accurately represents the average speed if the graph shows constant acceleration-- a straight line.

...Or at least that's what I got out of HW 8.

Nadia,

You are correct about only using the average of the initial speed and the final speed.

With that, how could we calculate the average speed for the graph on this post?
