Calculus Level 2

When ships come in to dock where the berths are extremely narrow, the ships needs to be towed in to prevent damage to both the dock and the ship. A metal cable is attached to the front of the ship, looped through a pulley that is hinged at the edge of the dock, and attached to an automated winch.

If the automated winch winds the cable at a constant rate, which of the following describes the speed at which the boat will be pulled in (prior to reaching the dock)?
