<human>:  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?
<bot>: How many hours does the movie take? ** The movie that is being replayed 6 times takes 1.5 x 6 = <<6*1.5=9>>9 hours.
How many minutes are in the advertisements? ** The advertisements before the start of the movie take 20 x 6 = <<20*6=120>>120 minutes in all.
How many hours are in the advertisements? ** One hundred twenty minutes is equal to 120/60 = <<120/60=2>>2 hours.
How many hours does the movie theater operate each day? ** Thus, the movie theater operates for 9 + 2 = <<9+2=11>>11 hours each day.
