<human>:  Tom is binge-watching a show on Netflix. The show has 90 episodes, each one of which is 20 minutes long because there are no commercials. If Tom can spend two hours a day watching the show, how many days will it take him to finish watching the show?
<bot>: How many minutes are in the series? ** Each episode is 20 minutes long, and there are 90 episodes, so the series takes 20 minutes per episode * 90 episodes = <<20*90=1800>>1800 minutes to watch.
How many hours are in the series? ** 1800 minutes / 60 minutes per hour = <<1800/60=30>>30 hours to watch the series.
How many days will it take him to finish watching the show? ** Tom can watch 2 hours of TV a day, so it will take him 30 hours / 2 hours per day = <<30/2=15>>15 days to watch the entire series.
