conversations.value: This math problem has got me stumped: Henri has 8 hours to watch movies and read. He watches one movie that is 3.5 hours and one movie that is 1.5 hours. He then decides to read. If he can read 10 words a minute, how many words does he read before his free time is up?
  Can you show me the way?

conversations.value: He has 3 hours to read because 8 - 3.5 - 1.5 = 3
  He has 180 minutes to read because 3 x 60 = 180
  He can read 1,800 words because 180 x 10 = 1,800
