Homework Statement
A boatman wants to cross a canal that is 3 km wide and wants to land at a point 2 km upstream from his starting point. The current in the canal flows at 3.5 km/h and the speed of his boat is 13 km/h.
(a) In what direction should he steer?
(b) How long will the trip take?
This is not for an actual course...this is from a textbook, but I am self teaching. I am having an issue finding out how they solved for this. I need a solution to this so I can understand it in the future.
The answers:
(a) At an angle of 43.4 deg from the bank, toward upstream
(b) 20.2min
