conversations.value: A movie that's 1.5 hours long is being replayed 6 times in one movie theater each day. There is a 20-minute advertisement before the start of the movie. How long, in hours, does the movie theater operate each day?
  Give me a solution to this problem

conversations.value: The movie that is being replayed 6 times takes 1.5 x 6 = 9 hours.
  The advertisements before the start of the movie take 20 x 6 = 120 minutes in all.
  One hundred twenty minutes is equal to 120/60 = 2 hours.
  Thus, the movie theater operates for 9 + 2 = 11 hours each day.
