"The Hungry Traveler and breaking bread"

A hungry traveler meets 2 men with some bread.

The first man has 5 loaves, and the second man has 3 loaves.

The two men generously put their loaves of bread into the center, and then they split the bread equally (3 ways).

After the meal, the satisfied traveler reaches into his pocket and pulls out 8 coins to compensate the men... He hands the first man 5 coins and the second man 3 coins, and then he leaves...

Later, the traveler realizes that he had split the coins incorrectly and paid each man the wrong amount!

Why? How should the traveler have divided the 8 coins among the two men?

On a bookshelf, there is a set of 10 classic math books. (properly arranged in order, Volumes 1 - 10).
Each book is identical in shape and size:
Front cover is 1/4" thick.
Back cover is 1/4" thick.
And, the cumulative page thickness of each book is 3".
One day a worm -- a bookworm?! -- gets onto the shelf and eats through some of the books:
If the bookworm began at page 1 of volume 1, and stopped at the last page of volume 4,
how many inches did the worm travel?
