An airplane is flying at a constant speed at an altitude of 10,000 feet 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 1/3π radians and is increasing at the rate of 1/60 rad/sec. Find the speed of the airplane
