Bob is reading a 300-page book. After one hour, he had finished 8% of the book. Assuming that he reads at a constant rate, how many more hours will it take him to read the rest of the book?
I answered this last night.

write this as an algebraic expression. a number divided by 4 is greater than or equal to 45.
To find out how many more hours it will take Bob to read the rest of the book, we need to first determine how much of the book he read in the first hour.
Given that he finished 8% of the book in one hour, we can calculate the number of pages he read in that time:
8% of 300 pages = 0.08 * 300 = 24 pages.
Now we know that he read 24 pages in one hour. To find out how many pages are left to read, we subtract the number of pages read from the total number of pages in the book:
300 pages - 24 pages = 276 pages.
Since we assume that Bob reads at a constant rate, we can divide the number of pages left by the number of pages he reads per hour:
276 pages / 24 pages per hour = 11.5 hours.
Therefore, it will take Bob approximately 11.5 more hours to read the rest of the book.
