conversations.from: assistant
conversations.value: If it took Hadassah six hours to paint 12 paintings, then she paints 12/6 = 2 paintings in an hour.
  If two paintings take an hour to complete, 20 paintings will take 20/2 = 10 hours.
  The total time she took to finish all the paintings is 10+6 = 16 hours.
