Answer 1

To find the number of additional pages Roman can type in 90 minutes compared to 60 minutes, we need to determine the difference in the number of pages typed per minute.

In this case, we know that Roman can type 3 pages in 60 minutes, which means he types 3/60 = 1/20 of a page per minute.

To find the number of pages he can type in 90 minutes, we can multiply the rate (1/20 of a page per minute) by the number of minutes (90):

(1/20) * 90 = 90/20 = 4.5 pages

Therefore, Roman can type 4.5 pages in 90 minutes.

To find the difference, we subtract the number of pages typed in 60 minutes from the number of pages typed in 90 minutes:

4.5 - 3 = 1.5 pages

Therefore, Roman can type 1.5 more pages in 90 minutes than in 60 minutes.
