There are four volumes of Twain's collected works on a shelf. The pgs of each volume are exactly 2 inches thick. The covers are each 1/16 inches thick. The bookworm started eating on pg 1 of volume 1 & ate through to the last pg on volume 4. What is the distance the bookworm covered?

Distance covered by worm
cover of 1st only 1 side = 1/16 inch
pages of vol 1 = 2 inches.
cover and pages of 2 volume. = 2/16 + 2
cover and pages of 3 volume. = 2/16 + 2
cover of 4th volume only 1 side = 1/16 inch
pages of vol 4 = 2 inches.
Total distance
= 1/16 + 2 + 2/16 + 2 + 2/16 + 2 + 1/16 + 2 =
= 6/16 + 8 = 67/8 inches = 8 integer 3/8 inches
