An airplane flies at an altitude of y = 5 miles toward a point directly over an observer (see figure). The speed of the plane is 400 miles per hour. Find the rates (in radians per hour) at which the angle of elevation 0 is changing when the angle is 0 = 30°, 0 = 60°, and 0 = 75°. y mi Not drawn to scale (a) e = 30° 30 X rad/hr (b) e = 60° rad/hr (c) e = 75° (Round your answer to two decimal places.) rad/hr
