Answer 2

9 books can three of these smart people read in 9 hours.

Step-by-step explanation:

6 smart people can read number of books in 6 hours = 12 books

1 smart people can read number of books in 6 hours = 12/6 = 2 books

1 person can read 1 book in = 6/2 = 3 hours

each one is reading one book in 3 hours.

Therefore, 1 people can read in 9 hours = 9/3 = 3 books

Since 3 people together are reading 3 books in = 3 hours

3 people together can read in 9 hours = 3 × 3 = 9 books

9 books can three of these smart people read in 9 hours.
