Answer:

I assume you want to know the rate of descent per minute

Rate of descent = -1000 ft/min

Where the negative sign signifies that the altitude is decreasing.

The rate of descent is 1000 feet per minute

Explanation:

At the beginning, the plane is at an altitude of 29,000 ft

After 20 minutes, it is at 9000 ft,

So, the rate is,

Rate of descent = (9000 - 29000)/20

Rate of descent = -20000/20

Rate of descent = -1000 ft/min
