A plane flying at 35,000 feet above the ground starts making a descent 150 miles from the airport. What is its angle of descent?
----------------------
Angle = -35000 ft/150 miles
----
-35000 ft = -35000ft/5280ft = -6.6288 miles
-------
slope = -6.6288/150 = -0.04419
----
Angle = invtan(-0.04419) = -2.5304 degrees

First, the units must be the same
150 mi x 5280 ft/mi = 792000 ft
The angle of descent is the angle whose tangent is
+35000+%2F+792000+=+.0442+
2.531 degrees
