How long will it take Marcus to read his book?

Answer :

Using division, we can find that Marcus will take 2 hours or 120 minutes to read the book.

Define division?

Repetitive subtraction is the process of division. It is the multiplication operation's opposite. It is described as the process of creating equitable groups. By dividing numbers, we divide a larger number down into smaller ones such that the larger number obtained will be equal to the multiplication of the smaller numbers.

Marcus is reading a book with 80 pages.

He reads first 20 pages in 30 mins.

So, to read 1 page time taken

= 30/20

= 3/2

= 1.5 mins

Now to read 80 pages, time taken will be:

80 × 1.5

= 120 mins.

Therefore, Marcus will take 2 hours or 120 minutes to read the book.
