An airplane flying at an altitude 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?

OpenStudy (anonymous):

Well it's decreasing by 1,300 feet every minute. So if that's how much it decreases in one minute, how much does it decrease in 15 mins?

12,500! Thanks!!
