The function below models the velocity of my pet turtle, Ned, as he walks in a straight line for a period of four minutes. 1) How far did the turtle walk over those four minutes? (The function is f(x)) 2) What is Ned's average velocity over those four minutes? 3) Click on the "Show Rectangle" box and drag point C. How can this rectangle be used to illustrate the idea of average value?
