A woman standing on a cliff is watching a motor boat as the boat approaches the shoreline directly below her. If the womans eyes are 250 feet above the water level and if the boat is approaching at 30 feet per second, how fast is the angle of depression of the boat from the womans eyes changing when the boat is 250 feet from the shore?
