Also, don't get discouraged by the downvote. I downvoted the question and voted to close it because at the moment, it is not up to site standards (you have shown no work you did on your own). If you edit your question so that you show what you tried and how far you got, I will not only remove the downvote, I will add an upvote.

So what you're looking at here is the sum of two vectors. You know the directions of both of them, but the length of the other is unknown. And you know the direction of their resultant vector. Therefore, you can solve for the length of the air speed vector.

I hope your course notes, textbook, or instructor have said how to interpret "S 81° 27' W," because that's not how actual aviators specify a course angle. A good first step would be to draw a figure showing the approximate angle between that course and the wind from due north.
