A woman walks due west on the deck of a ship at 3 mi/h. The ship is moving north at a speed of 23 mi/h. Find the speed and direction of the woman relative to the surface of the water. (Round your answers to one decimal place.)

2. Relevant equations

3. The attempt at a solution

First I drew the picture:

EDIT: Attachment

Then I solved the relative velocity formula:

[itex]v_{w/g} = v_{s/g} + v_{w/s}[/itex] = 23 + 3 = 26mi/h

Which went wrong, so I made another attempt:

[itex]\sqrt{23^2 + 3^2} = 23.2[/itex]

And i don't know how to find the angle. Should I do it like arctan(23/3) ?

Thanks in advance,
