A woman walks due west on the deck of an ocean liner at 4 mi/h. The ocean liner is moving due north at a speed of 30mi/h. Find the speed and direction of the woman relative to the surface of the water
-------------
North is 360 degrees
West is 270 degrees.
----
It's a right triangle.
speed = sqrt%284%5E2+%2B+30%5E2%29
=~ 30.265 mi/hr
---------
The angle is atan(4/30)
=~ 7.59 degs (west of north)
= 352.41 degs
