An object dropped from rest from the top of a tall building on Planet X falls a distance d(t) = 7t feet in the first t seconds. Find the average rate of change of distance with respect to time ast changes from t, = 3 to t, = 9. This rate is known as the average velocity, or speed. feet The average velocity as t changes from 3 to 9 seconds is sec (Simplify your answer.)

A driver of a car stopped at a gas station to fill up his gas tank. He looked at his watch, and the time read exactly 3:40 p.m. At this time, he started pumping gas into the tank. At exactly 3:44, the tank was full and he noticed that he had pumped 10.7 gallons. What is the average rate of flow of the gasoline into the gas tank?
Use the table of values you made in part 4 of the example to find the limiting value of the average rate of change in velocity.
