Hi, can you please show us the diagram you drew and the work you have done so far? It really is hard to help you if we do not know where you are stuck.

You do know that R*T=D? Do you see the right triangle formed by the ship? I am sure that Pythagoras see's the right angle.

See where you can get with the above hints.
