Answer to POW #9:

The camel can get 533 bananas to the other side of the desert. (Actually, he can bring 533 and 1/3, if you want to be picky.) Here is a hint for the solution: Start by having the camel take 1000 bananas 200 miles; he will consume 200 on the way, leave 600 there, and consume 200 on the way back. Then... you work it out!
