A drone is moving horizontally at a constant speed of 200 200 meters per minute at an altitude of 300 300 meters. It flies directly above an observer standing on the ground. Determine the rate at which the angle of elevation (between the ground and the line from the observer to the drone) is changing 4 4 seconds later.

− 1350 2029 rad/min -\frac{1350}{2029}\text{ rad/min}
