A starving beetle starts easting at page one of volume one and eats straight through to the last page of volume four. How many centimeters does the beetle travel?
We normally arrange books in order from left to right. (The same direction as we read English) When books are arranged on a shelf they are front cover of Book 1 to rear cover of Book 2, etc.

So the answer is 17 CM. All the way through Books 2 and 3 (16 CM), and the front cover of Book 1 (0.5 CM) and rear cover of Book 4 (0.5 CM). The bug starts touching Book 1 page 1 and ends touching Book 4 last page, he does not need to eat through those pages to meet the requirements of the puzzler. (Must be a pretty flat bug to take up no space when he starts out.)

Congratulations, John H! You're the Professor Bumble winner.

Congratulations to T-Square! 17 cm is correct!

T-Square was cleaning out his old barn. He was dragging things out into the yard and filling containers with useless items he had collected over the years. At one point, he rolled an old barrel out of the barn which weighed 20 kg. T-Square put something in the barrel and when he was finished, it weighed less.

What did T-Square put in the barrel?

And for the Math-heads:

When asked how old he was, John H replied, "In two years I will be twice as old as I was 5 years ago."

How old is he?

Bonni,

How'd you know what I was doing? : You got spys around here? : Do I have to be careful around here? : I know its a small town but this is rediculous. Now, I'm going to be more paranoid than normal. Guys, she's picking on me, help. :




It's ok, the guys in the white suits are here. They're saying for me its time to take my pretty purple pill. Then they have this pretty white jacket with the long sleeves for me to wear. Aren't they nice.............................................. .................................................. .................................................. .......

How old is he?
X + 2 = Y

Y = 2(X - 5)

X+2=2(X-5)

X+2=2X-10

12=2X-X

12=X

Don't you just hate math geeks.

Skier_j and T-Square are correct on the age question!

Any guesses on the barrel question?

I'll go with a hole.

helium - if it was an airtight container
hole is prob the right answer

What did T-Square put in the barrel?
A stick of dynomite with the fuse lit
(however, I like "a hole" as the real answer)

Here's one for the young kids:
Which weighs more; 10 pounds of feathers or 10 pounds of bricks?
post #45 of 53
Ding, ding, ding! HOLE is correct!

I can't answer the above question (too easy). Since we're into easy ones, riddle me this, kiddies:

If three cats can catch three mice in three minutes, how many cats would be needed to catch 100 mice in 100 minutes?
post #46 of 53
Three.
post #47 of 53

Number(s)?

Divided by 10 the remainder is 9
Divided by 9 the remainder is 8
Divided by 8 the remainder is 7
Divided by 7 the remainder is 6
Divided by 6 the remainder is 5
Divided by 5 the remainder is 4
Divided by 4 the remainder is 3
Divided by 3 the remainder is 2
Divided by 2 the remainder is 1

Correct, ssh. Each cat can catch one mouse per minute.
post #49 of 53
Actually, they catch an average of a mouse per minute between them. So, they each catch one every three minutes...

Flaw, after 3 or 4 mice they will be full and you need to bring on more cats.
