Question

An airplane 30,000 feet above the ground begins descending at the rate of 2000 feet per minute. Assume the plane continues at the same rate of descent. Write an equation to represent the height of the airplane in feet above the ground f(x) in relationship to time in minutes x

Answer 1

`f = 30000 - (2000 * m)` is an equation to represent the height of the airplane in feet above the ground f(x) in relationship to time in minutes x

Explanation:

As given that the plane is at 30000 feet above the grounds. And starts descending at the rate of 2000 feet/ min

So, let us consider the below,

H= height in feet above ground

r = rate of descent

m = minutes

So, now frame the required equation format with the given data as follows,

`H = 30000 - (2000 * m)`
