There is a room, 20 feet long. The room is 10 feet wide and 10 feet high. On one end of the room is a spider one foot from the bottom equally spaced (5 feet) from each side. On the other end of the room is a fly. He is one foot from the top equally spaced (5 feet) from each side. The question is: What is the shortest difference that the spider has to travel to eat the fly? Hint: it is a lot less than 30 feet. The spider does not hop or jump .. he walks as normal.

The spider can go straight up 9 feet, go over 20 feet, and down 1 to get the fly, a total distance of 30 feet.
Or he can sit down and think hard and do some math and figure out that he can actually do it in only 29.53 feet, but by the time he finally gets to the fly, it's gone already. Serves him right for being a wiseguy.

The spider never travels farther than the end of his web,
The flies come to him and they get stuck on the web.
