An airplane flying at an altitude of 31,000 feet descends at a rate of 1,200 feet per minute. If the plane descends for 15 minutes, what would its altitude be in feet?: *

13,000
23,000
18,000
21,000

Calculate how far it falls in 15 minutes and subtract that from the original altitude

i need the dafaniton and a picture

i mean of altitude a definition and picture

1200*15 = 18,000

31,000 - 18,000 = 13,000 ft.

13,000 meters

To find the airplane's altitude after descending for 15 minutes, we can use the formula:

New altitude = Initial altitude - (Rate of descent * Time)

In this case, the initial altitude is 31,000 feet, the rate of descent is 1,200 feet per minute, and the time is 15 minutes.

Plugging in these values into the formula:

New altitude = 31,000 - (1,200 * 15)

First, we calculate the product of the rate of descent and the time:

1,200 * 15 = 18,000

Next, we subtract the product from the initial altitude:

31,000 - 18,000 = 13,000

Therefore, the airplane's altitude would be 13,000 feet after descending for 15 minutes.

So the correct answer is:
13,000 feet
