And if the notion of average velocity or average value of a function is completely foreign to you, I encourage you to watch the videos on Khan Academy on finding the average of a function. But straight, just to kind of cut to the chase, the average velocity, the average velocity is going to be the area under the velocity curve divided by our change in time. So the area under the velocity curve from t equals zero to t equals 10 of b of t, of b of t, dt, divided by our change in time. So it's going to be divided by, well, you're going from zero to 10, so 10 minus zero is going to be equal to 10. And if you wanted the intuition here, it's like, well, if you know the area of something, and if you wanted to find its average height, you could just divide by its width, and that's what we're doing here. If we know the area of something, we want to figure out its average height, and so you divide by its width. That's, I guess, a very high level intuition for where this expression came from.
