Remember
the busy Bee? The one that kept flying from the bicyclist to his home and back as he approached it?
Well, at the instant when the person finally got to his house, which way was the Bee facing? (Assume that the Bee's turns are instantaneous - that it can go from facing the house to facing the cyclist in no time.)
Let's go backwards and assume that bee is facing something and the time is up. If it can change its direction in no time then it can change its direction twice in no time so there is no solution, as the bee turns and turns infinite number of times in no time :).
