A sailboat is headed east at 18 mph relative to the water. A current is moving the water south at 3 mph.
a. What is the angle of the path of the sailboat?
tan(A) = 3/18
Angle =~ 9.46 degs
--> a path of 99.46 degs (090 or 90 degs is East)
--------------
b. What is the sailboat's speed with respect to the ocean floor?
r =~ 18.25 mi/hr
