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?

Well since this in the category general and not in just math I'll try thinking outside of the box. Fist the man jumps in and swims underwater so the tiger can't see him. If he gets far enough then its a matter of the tiger getting to the point opposite of where he is standing by the time you reach there.
