Related rates problem. I have no problems with implicit diff or solving, but having difficulty setting up the equation:
(Airplane problem). A military plane maintains an altitude of 15,000 feet over a vast flat desert. It flies at a constant speed on a line that will take it directly over an observer on the ground. At noon, the angle of elevation from the observer to the plane is 30 degrees, and the angle of elevation is increasing at a rate of 2.2 degrees per second. Find the speed of the plane at noon. Round off your answer to five
significant digits. What is the speed in miles per hour
