Question

Airplane is flying at 9000 feet.It begins descending at a rate of 500 feet per minutes write an equation

Answer 1

9000 - 500m

Explanation:

Your original number is 9000. It starts to decrease at a rate of 500 feet per minute. So we know that you will subtract 500 from 9000 but we don't know how many times. Because of this, we will put a variable to represent the minutes that we are descending.

In conclusion: 9000 - 500m
