Question

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?

Answer 1

Answer:

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

$10,000 feet= 1.8939 miles$

$\frac{10,000 feet}{1.8939}=1 mile$

1 mile = 5280.10 feets

Answer 2

There are 5280 feet in a mile.
