How do I answer this question:

As a ship is approaching the dock at 45.0 cm/s, an important piece of landing equipment needs to be thrown to it before it can dock. This equipment is thrown at 15.0 m/s at 60.00 above the horizontal from the top of a tower at the edge of the water, 8.75 m above the ship's deck (Fig. 3.46.) For this equipment to land at the front of the ship, at what distance D from the dock should the ship be when the equipment is thrown? Air resistance can be neglected.
