A boat is pulled into a dock by means of a rope attached to a pulley on the
dock. The rope is attached to the front of the boat, which is 6
feet below the level of the pulley.
If the rope is pulled through the pulley at a rate of 16
ft/min, at what rate will the boat be approaching the dock when
90 ft of rope is out?
The boat will be approaching the dock at ft/min.
Hint: Sketch a diagram of this situation.
