A square medieval castle on a square island was under siege. All around the island, there was 10 metres wide water moat. But the conquerors could make foot-bridges only 9.5 metres long. Nevertheless a wise man was able to figure out how to get over the water. What do you think was his advice?
(There's a place on the other side to put the bridge against, not just a sheer wall. Water moat has square corners - that section of the moat is about 14.1 metres wide.)
just walk across the moat, it's not that deep =p

ReplyDeleteYou can put one foot-bridge over one corner (thus a triangle is created). Then from the middle of this foot-bridge lay another foot-bridge to the edge (corner) of the castle.
