how long you take time to finshreading a book of 100 pages?

It depends on the level of the book, for kids book sometimes i'm done in 20 minutes, and for adut level books, It can take me to around an hour.

This topic reminds me of an instance and I'd like to share it here.
I own a book of around 120 pages, and I started it last year (that was the first novel I read).
I read just 2 pages everyday and even less, later. lol..
It took me more than 7 months so finish that book of mere 120 pages!!
I believe I made an entry into Guinness Book of Records..

It really depends on the book, in question. The book that I am reading will determine how long it takes me to read a book that long. Depending on the book, it could take 25 minutes, like it could take me an hour or so.

It really does depend on the number of lines on a page and the size of the words in the page. If the words are big then it will only take abt 15 mins. But if the font is really small it will take more time and i will take more than an hour to read it

I think I can finish the 100 pages book in few hours, I don't read fast, but when I'm into it, I wont put it down until I finish it, lol. But I guess, like the other responses says, it all depends on the book.

Well it depends on the type of book I read.If I find the book interesting I will read it within a single day or utmost two days.But there are some books which I have started reading, a long while ago and has not yet finished it.I finished some of the books like Alchemist within a single day.

It doesn't matter how difficult or convoluted the story is, it would take me less than an hour.
