conversations.value: Tom reads 10 hours over 5 days.  He can read 50 pages per hour.  Assuming he reads the same amount every day how many pages does he read in 7 days?
  Give me a clear explanation.
conversations.from: assistant
conversations.value: He reads 10/5=2 hours per day
  That means he reads 2*50=100 pages per day
  So he reads 100*7=700 pages in 7 days
