Yes... this is homework, but I'm completely stomped..
Here's the situation: there are three animals that need to cross a river: a dog, a cat, and a mouse. Only one animal can go across at a time, BUT if the dog is left with the cat, the cat will be eaten. If the cat is left with the mouse, the mouse will be eaten. How do they go across the river one at a time without any of them getting eaten?
I'm thinking that the cat has to go first because the dog will not mess with the mouse... but then if I take either the dog or mouse over next, either the cat or the mouse will be eaten. Any ideas?
My dad suggested that I let the cat eat the mouse, and the dog eat the cat - and they all go over in one trip... (in the dogs stomach--but then 2 of them will be eaten...) ??
