April 2015: The 10 Commandments, Let's Make a Deal, A&W root beer, and the bookworm

(from April 26, 2015)

"The Bookworm"

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?
