Answer 3

Time Needed for Repairing Books

To calculate the time needed for repairing a different number of books, we can use the given information that it takes Kostya 3 hours to repair 2 books.

Time needed for repairing 4 books: To repair 4 books, we can use the following calculation: 3 hours for 2 books → 3/2 = 1.5 hours for 1 book 1.5 hours for 1 book × 4 books = 6 hours for 4 books

Time needed for repairing 6 books: Similarly, for 6 books: 3 hours for 2 books → 3/2 = 1.5 hours for 1 book 1.5 hours for 1 book × 6 books = 9 hours for 6 books

So, to repair 4 books, Kostya would need 6 hours, and to repair 6 books, he would need 9 hours.
