Question 620638
Speed and Direction of a Ship. A ship's captain sets a course due north at 12 mph. The water is moving at 10 mph due west. What is the actual velocity of the ship, and in what direction is it travelling?
------------
The speed = {{{sqrt(12^2 + 10^2) = sqrt(244)}}} mi/hr
--------
The angle wrt due North = atan(10/12) =~ 39.8 degs
--> track of 320 degs
