1. 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
