Question

To approach the runway, a pilot of a small plane must begin a 10 descent starting from a height of 1983 feet above the ground. To the nearest tenth of a mile, how many miles from the runway is the airplane at the start of this approach. . A. 2.2 mi. . B. 0.4 mi. . C. 11,419.6 m.

Answer 1

sin10 = 1790/d

d = 1983/(sin 10)

d = 11665 feet

Since there is 5,280 feet in one mile we have

11665/5280 = 2.2 miles
