Ash "the working bee" decides to gather pollen and in her quest flies 50 meters from a beginning point at 0° along the west and finds nothing. She then turns 90° south for approximately 100 meters to find nothing once again. She then decides to fly 150 meters southwest to once again disappoint. The frustrated bee on her way back flies 200 meters east and finds a plant to gather pollen. The happy bee then decides to fly back home for 25 m in the northeast direction. Determine the displacement and direction of the bee.
