conversations.value: 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?
  Give me a detailed solution.
conversations.from: assistant
conversations.value: 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
