conversations.value: It takes James 10 minutes to read 3 pages of his book before he goes to bed. He reads 18 pages of his book and then decides to go to sleep. How long does James spend reading, in minutes?
  Give me a solution to this problem

conversations.value: James would take 18 ÷ 3 = 6 times longer if he read all 18 pages.
  This means James would spend 6 × 10 = 60 minutes reading.
