A boat is pulled in to a dock by a rope with one end attached to the front of the boat and the other end passing through a ring attached to the dock at a point 12 ft higher than the front of the boat. The rope is being pulled through the ring at the rate of 0.21 ft/sec. How fast (in ft/s) is the boat approaching the dock when 13 ft of rope is out? Note: Round to the nearest hundredth. Speed is always positive.
