An airplane descends in altitude from 20,000 feet to 10,000 feet. a gauge at radar traffic control reads that the airplane's altitude drops 1.8939 miles. how many feet are in a mile?

There are 5280.10 feets in 1 mile.

Step-by-step explanation:

Initial altitude of an airplane = 20,000 feet

Final altitude of an airplane = 10,000 feet

Drop in an altitude of an airplane = 20,000 feet - 10,000 feet = 10,000 feet

Drop in an altitude of an airplane read by radar traffic control is 1.8939 miles

1 mile = 5280.10 feets
