An airplane is flying at a constant speed at an altitude of 10, 000 ft on a line that will take it directly over an observer on the ground. At a given instant the observer notes that the angle of elevation of the airplane is - n radians and is increasing at the rate of 3 rad/sec. Find the speed of the airplane. 60 a
