Question

An airplane begins its descent. After 4 minutes, it is 22,000

Answer 1

Answer:

2,000 feet/minute

Step-by-step explanation:

After four minutes the plane has descended to 22,000 feet, and after seven minutes it has descended to 16,000 feet, so the plane lost 6,000 feet of altitude in three minutes. Assuming it lowers at a constant rate of change, the rate of change of the airplane would be $\frac{6000}{3}$ or 2,000 feet/minute.

Answer 2

This is so hard
