You are at a point A on the shore of a circular lake with radius R. You want to get to the point B which is diametrically opposite from A. There is a boat at A. You could row in a straight line from A to B. You could also run around the lake all the way from A to B. Or you could row the boat from A to some point C on the coast somewhere in between A and B, abandon the boat, and then run to B. Assume that you can run with velocity v₁ and that you can row with velocity v2. Assume v2 < vi (otherwise, the problem is very easy, can you see why?) Where should the point C be located in order to get from A to B as fast as possible? Your answer will, of course, depend on the values of v₁ and v2. C A •В B Hint: Depending on what approach you take, half-angle formulas might come in handy, so you should look them up.
