Volumes 1 and 2 of a two-volume set of math books sit next to each other on a shelf. They sit in their proper order: Volume 1 on the left and Volume 2 on the right. Each front and back cover is 1/8 inch thick, and the pages portion of each book is 1-inch thick. If a bookworm starts at the first page of Volume 1 and burrows all the way through to the last page of Volume 2, how far will it travel?

Since each book is 1/8 inch thick

The distance travelled = 1/8 + 1/8 = 2/8 = 1/4
