Given a 10' x 10' hole which is very deep, how do you walk across the hole using two boards that are each 9' long?
You can't jump, pole vault across, nail the boards together, or go around the hole.
You can start on any side you like, but once you start to cross, you must stay on the two boards. No stepping off on the sides.
Answer
You put the first board
at a 45 degree angle across one corner
of the hole. Then you put the other one
with one end on the first board and the other end on the side of the hole.
Thanks to Julian Rosen and Geobits for their insight on how my drawing was bad. I updated it to be more accurate:
