A lighthouse is on an island 400 meters east of the shore of Lake Latasha. The lighthouse beam makes a full turn every 13 seconds. Ellie is standing on the shoreline at a point 1500 meters from the lighthouse. How rapidly is the point where the beam meets the shoreline moving along the shoreline when the beam passes through Ellie's position? (Assume the shoreline runs north/south) (enter your answer rounded to 3 decimal places; be sure to include the units of your answer) Show or upload your work below.
