A dock sits above the water. A rope is attached to a pulley on the edge of the dock. The pulley is located 5ft vertically above the water on the dock. The other end of the rope is attached to a float floating on the water. The rope is pulled in at a constant rate of 3 ft/s. How fast is the float traveling on the surface of the water (towards the dock) at the moment when the boat is 12ft from the dock? Hint: The edge of the dock, down to the water, then over to the float, makes a triangle.
