A ship cruises forward at vs = 4 m/s relative

to the water. On deck, aman walks diagonally

toward the bow such that his path forms an

angle θ = 30◦ with a line perpendicular to

the boat’s direction of motion. He walks at

vm = 5 m/s relative to the boat.

Here's a picture.

2. Relevant equations

I'm not sure, I didn't use any equations. I solved it by breaking the velocity into vector compeonents.

3. The attempt at a solution

I do the sin of 30 and multiply that by the man's velocity on the ship 5m/s , which would give an x velocity, or his velocity relative to the water, of 2.5m/s. Then, I add the speed of the ship to his velocity which gives me 6.5m/s, but my answer is not correct. What is wrong with my process
