3. Let d(t) = 30 feet continue to be the distance function with respect to time (in seconds) of the car. We are going to compute the average velocity of d over the following smaller and smaller intervals: [3, 3+h], where h = 1, 0.1, 0.01, and 0.001. a. Write an expression for the average velocity from t = 3 to 3 + h. (5 points, 3 points for the steps/process and 2 points for the answer in simplest form) b. Use the simplified expression in part (a) to calculate the AROC where h = 1, 0.1, 0.01 and 0.001. (2 points each)
