Q- A boat is trying to get from point A to point B, which is exactly to the east of A. The ocean current is due north at 4.8 km/h. The boat speed relative to the water is 18 km/h.
a) If the captain heads his boat due east, what will be his actual course relative to the shore?
b) To attain a straight course, due east, what should be the heading of the boat?
