Question

An airplane at 30,100 feet above the ground begins descending at the rate of 2150 feet per minute. Write and solve a linear equation to find how many minutes it will take the plane to reach the ground

Answer 1

30100-2150x and it would take 14 minutes to reach the ground.

Explanation:

30100 feet is out starting y coordinate, and since 2150 is always changing depending on the amount of time we multiple it by x (the amount of minutes) therefor we can create the equation 30100-2150x and when we plus in 14 the equation would equal 0
