     Here is another rather interesting clock problem that was on the Putnam
last year. If you have a standard clock with hand lengths 3 and 4, how far
apart are the tips of the hands when the distance between them is increasing 
most rapidly? A freshmen calculas student has the tools to solve this but
a little care needs to be taken or you can fill  a wall with the equations.
