K An object dropped from rest from the top of a tall building on Planet X falls a distance di(t) = 5t feet in the first t seconds. Find the average rate of change of distance with respect to time as t changes from t₁ =4 to t₂ = 10. This rate is known as the average velocity, or speed. The average velocity as t changes from 4 to 10 seconds is (Simplify your answer.) 13 feet sec ***

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?
