Then over here, then he accelerates. Over here, it seems like his rate of change of distance, which would be roughly, or you could view it as the slope of the tangent line at that point, it looks higher than his average. And then he starts to slow down again. And when you all average it out, it gets to 23 and 1 1 half miles per hour. And I looked it up. Usain Bolt's instantaneous velocity, his peak instantaneous velocity, is actually closer to 30 miles per hour. So the slope over here might be 23 whatever miles per hour.
