. A plane was flying at an altitude of 30,000 feet when it began the descent toward the airport. The airplane descends at a rate of 850 feet per minute.
a. What is the function rule that describes this situation?
b. What is the altitude of the plane after it has descended for 8 minutes? Show
your work
c. Use the function in part a to determine how long it takes for the plane to
land if it descends at a continuous rate.
