An airplane flying at attitude of 32,000 feet descends at a rate of 1,300 feet per minute. If the plane descends for 15 minutes, what would its altitude be in feet ?

Final answer:

To find the final altitude of the airplane after descending for 15 minutes, subtract the total descent distance from the initial altitude of 32,000 feet. The final altitude is 12,500 feet.

Step-by-step explanation:

To find the altitude of the airplane after descending for 15 minutes, we need to calculate the total descent distance. The descent rate is given as 1,300 feet per minute.

So, in 15 minutes, the airplane would have descended a total of 15 * 1,300 = 19,500 feet. To determine the final altitude, we subtract the descent distance from the initial altitude of 32,000 feet.

Hence, the final altitude of the airplane would be 32,000 - 19,500 = 12,500 feet.

Since the plane descends 1,300 feet per minute it would descend 19,500 feet after 15 minutes (1,300 x 15 = 19,500) Subtract this from the plane's initial altitude 32,000 and the new altitude will be 12,500. (32,000-19,500=12,500)
