easy - three marbles is the minimum although, thats if you are lucky.

No, that's not it. Less. And the answer has no luck involved. You will know!

samhussey got the shirt thing right.




marbles needed to be pulled: one
I won't say why, though, because I don't want to ruin it. =)

That's the ticket. You've done this before.

Agree, Going back to the train and the super bird, Mathematically you will have to use a litle more complicated math than cal Philosophically speaking the answer is infinite, Reality wise, the trains are gonna crash and the bird is going to die in the midle.;)

How about the two trains going on the same track opposite directions. the distance between the trains in 100 miles, and they travel at 100 miles per hour. A super bird goes from train A to train B touches it and comes back to train A touches and goes back to train B, the super bird travels at 150 miles per hour.
How many trips the bird have made before the trains collide?

100MPH 100MPH
--------------> <--------------
A_______________________________________________B
100 MILES



I answered wrong the first time. Thought it was how far the bird flies (got it wrong too, it's only a half hour or 75 miles). The answer isn't infinity number of trips, since the bird stops flying once the trains are closer together than the length of the bird (or that type of thought). The rest is left as an exercise for the student. Assume the bird is 100 miles long, then one trip is the answer (it's a big bird).

So .....
You have $100, you must spend it all.

You need to buy exactly 100 animals.

You can't buy half an animal, but you buy at least one of each.
On offer are Cows for $10 each
Pigs for $3 each
and Hens for 50 cents each.

How many of each animal must you buy?

Orders please....

Skydiving is easy. All you have to do is relax while plummetting at 120 mph from 10,000' with nothing but some nylon and webbing to save you.

That's my answer. ONE PIG of a problem.

actually, chicken is fairly lean and I don't need pig or cow (mmmm, ribs). how about 100 chickens and $50 for mixed drinks??

I like your answer better too.

8 pirates and a monkey are marooned on an island. The pirates collect coconuts and agree to divide them up in the morning.

During the night a pirate wakes up and thinks his colleagues will steal his share, so he takes and hides 1/8 of the coconutrs, throws a coconut to the monkey, and returns to sleep. Shortly after another pirate wakes up, takes 1/8 of the remaining coconuts and hides them, throws one of the remainder to the monkey, and goes back to sleep.

Then another pirate awakes and does the exact same thing. And then the next, and then the next, etc. until each pirate has done it.

In the morning they share the remaining coconuts equally, and finding a remainder of one, they give it to the monkey.

What is the smallest number of coconuts they could have started with?

A Vogon galactic highway construction crew finds a small spherical rocky planet in its path and decides to bore (by vaporization) a cylindrical tunnel right through the center of the planet. Since they are paid piece rates, they have to measure the length of the resulting tunnel. It turns out to be exactly 1 Vogon mile in length.

What is the volume of the remaining rock in the planet?

There was a time I could solve this with a pencil and paper using algebraic formulas and such. Microsoft Excel works well, too... see attached.

As someone earlier said, Achilles and his opponent, the tortoise, will be neck and neck at 11.1111111111 meters. One moment after that, Achilles will be ahead.
