A man is standing on a rock in the middle of a circular lake of radius 1. There is a tiger on the shore of the lake that can run four times as fast you can swim, however the tiger can not swim. The tiger is hungry and always attempts to keep the distance between the two of you at a minimum.

How can you safely swim to shore?

Looks to me like Charlie solved this problem, provided that once ashore the man can maintain or increase the pi-3 distance between himself and the tiger.
