Kelly read 30 pages of her 300 page book on 6 hours at this rate how long will it take her to read the entire book

Take 300 and divide it by the number of pages already read.

300 / 30 = 10

Now multiply this by the number of hours required to read the initial 30 pages.

10 x 6 = 60

So, since it takes Kelly 6 hours to read 30 pages, it should take Kelly 60 hours to read the 300 page book.
