## Homework Statement

A ship travelling 55 degrees [W of N] is 65km farther north after 3.0h. What is the ship's velocity.

## Homework Equations

sin, cos, tan?

## The Attempt at a Solution

I know that Vground= Vair + Vwind, and that Vground = Vboat + Vcurrent, but i'm not sure if that is even relevant to the question... So far I have drawn out :

Do I add these vectors together or subtract? and am I trying to find the boat's velocity or ground velocity. I think boat velocity but what does that make of the 55 degrees W of N... I am so lost please help (:
