Question

An airplane 30,000 feet above the ground begins descending at a rate of 2,000 feet per minute. Write an equation to model the situation. Find the altitude of the plane after 5 minutes

Answer 1

A = 30,000 - 2000m where A=altitude and m = number of minutes

After 5 minutes A ( altitude) = 30,000 - 2000(5) = 20,000 feet
