conversations.value: Yesterday Ryan got five books from the library. They were a total of 2100 pages. His brother got one book a day that was 200 pages each. They both finished them in a week. On average, how many more pages per day did Ryan read compared to his brother?
  Give me a detailed solution.

conversations.value: Ryan read an average of 300 pages a day because 2100 / 7 = 300
  He read 100 more pages a day on average than his brother because 300 - 200 = 100
