Depends on your personal reading speed, your powers of concentration, how many interruptions you have, and how much time you have.
No less than an hour honestly. Two hundred pages is really not a lot.
It depends entirely on how interesting it is. It could take me either a couple days or a lifetime
Four hours, unless the book is non-fiction.
How long is a piece of string? it could take 200 years if you read a page a year, and realistically about a day and a half. If this is a school assignment read with with a notebook and pen beside you and make notes about the main characters and plot points - anything you're likely to be asked about in a test or class discussion. Then it will take a bit longer.
At one page day?
If not many words like around a few hours. It can take so many hours, like 10 or more.
Really depends on the topic, the reader, the print size, etc. It would take me around 2 1/2 hours on average, but I am a really fast reader. Probably would take around 6 or 7 hours if you take it slowly.
Read five pages in the book or one like it (a novel, a textbook), and multiply by 40 and add some time for breaks.
IT takes me about an hour and a half.
depends whether it is technical or a novel and whether I like it enough to read more than 5 pages. But a novel I like probably an hour.
