Answer :
If an airplane descends from an altitude of 32,000 feet above sea level to an altitude of 27,000 feet above sea level then the change in altitude is -5000 feet.
Given that an airplane descends from an altitude of 32,000 feet above sea level to an altitude of 27,000 feet above sea level.
We are required to find the change in altitude of airplane.
Altitude or height is basically distance measurement, usually in the vertical or up direction, between a reference datum and a point or object.
Altitude before descending of airplane=32000
Altitude after descending of airplane=27000
Change in altitude=27000-32000
=-5000
Hence if an airplane descends from an altitude of 32,000 feet above sea level to an altitude of 27,000 feet above sea level then the change in altitude is -5000 feet.
