A bookworm’s meal

Stumbled on this one when I was doing research for my new site, haven’t seen this around before, so I thought I’d throw it out here:

An hour, I think?

10mm + 10mm + 1mm + 1mm = 22mm
Pages + Pagse + BackCover + Frontcover

22 * .5 = 11 hours

Adrian is right. Dave is wrong. Look *carefully* at the
illustration.

I suppose it depends on your cultural perspective... If the books were in Chinese (for instance) then Dave's answer would be correct!

Oh, come on... Don't make me go and add to the problem that the books are in english, I think it's a pretty safe assumption to make they are your regular left to right variety... :)

Well, okay... but I do wonder about the proportion of left-to-right vs right-to-left books in the world.

The aha factor on this one is pretty high ;-)

Yes, yes it is. Thankfully, I chose not to disclose the AHA factor up front on my site, only difficulty :)

who says the books aren't upside down?

The picture does :) the digits "1" and "2" are clearly right side up. Any more nitpicks?

The part of this statement that I find interesting is the "haven’t seen this around before" part.

The first time I saw this puzzle was about 40 years ago and I wouldn't be surprised if it was already 40 years old then.  It is quite a simple problem, but must have just the right aha factor to keep it popular all this time.

Actually, what I meant to say was that I haven't seen this problem around *here* before.  :)

I readily believe this problem is very old, since all the good ones seem to be :)
