Answer 2

Calculation of the Number of Pages in the Book

To determine the number of pages in the book, we can use the information provided about the reading speeds of Olya and Dima, as well as the time it took Olya to finish reading the book.

According to the information given: - Olya reads 50 pages in 1 hour. - Dima reads 30 pages in 1 hour. - Olya finished reading the book 36 minutes earlier than Dima.

To find the number of pages in the book, we can set up the following equation:

Olya's reading time = Dima's reading time + 36 minutes

Let's calculate the reading times for Olya and Dima:

- Olya's reading time: 1 hour = 60 minutes - Dima's reading time: 1 hour + 36 minutes = 96 minutes

Now, let's calculate the number of pages in the book using the reading speeds:

- Olya's reading speed: 50 pages per hour - Dima's reading speed: 30 pages per hour

To find the total number of pages in the book, we can use the formula:

Total number of pages = Olya's reading speed * Olya's reading time

Let's calculate the total number of pages in the book:

- Olya's reading speed: 50 pages per hour - Olya's reading time: 60 minutes

Total number of pages = 50 pages/hour * 60 minutes = 3000 pages

Therefore, the book contains 3000 pages.
