Hare has challenged the tortoise to a revenge race. Tortoise accepts, but tells hare that any revenge race must be across the rickety bridge. That should help tortoise, because it stops the hare from getting into her jumping rhythm. You can see it is pretty rickety… Here is the bridge with five struts that will break if stepped upon – plunging our poor hare to almost certain death in the torrent below. The hare will win the race if she can make three hops of equal length… The tortoise wins if the hare cannot find three safe and equal jumps in a row. Otherwise the hare wins. So who wins on each bridge? Try a few of the different bridges below. Can you create your own bridge that guarantees the hare will not win? Source: mathpickle.com
