OK, Bob, sounds like a plan. A hockey book. .... hmmm. I already have 
one problem in mind that is a takeoff on the mowing problem:

If  Zamboni A can clean the ice surface in 5 min and B takes 10 min, how 
long would it take for both to do it assuming no interference?  

On a more serious note, to get ballpark numbers (scuse me, hockey rink 
numbers) for a cleaning time I would base it on my observances, maybe 10 
swipes of the length of the rink, maybe 30 sec per swipe, so 300 sec or 
5 min or so would be reasonable.

Sorry to you all for the physics-geekness here.

Have a good rest of the weekend.
