Meso can type 15 pages in 5 minutes. Tyler can type the same 15 pages in 3 minutes. How many minutes would it take Meso and Tyler to type 40 pages working together? Let's be accurate as possible.
Meso types 15 pages / 5 minutes = 3 page per minute. Tyler types 15 pages / 3 minutes = 5 pages per minute. Together they can type 3 + 5 = 8 pages per minute. Working together, it would take them 40 pages / 8 pages per minute = 5 minutes.
The answer: 5.
