Amaya is watching a movie that she finds kind of boring, so she keeps tuning out and having to rewind it to catch what she missed. She watches 35 minutes before she realizes she needs to rewind the movie to catch something she missed, a process that adds 5 minutes to her total viewing time. She watches the movie for another 45 minutes but has to rewind it again, adding 15 minutes to her total time. Finally, she watches the last 20 minutes uninterrupted. If she added up the duration of the film plus all the times she had to rewind and re-watch parts, how many minutes did it take her to watch the movie? Let's answer step by step:
Amaya watches the movie without rewinding for 20 minutes + 15 minutes + 45 minutes + 20 minutes = 100 minutes duration of the movie. However, Amaya also spent extra time re - watching parts she rewound, for 5 minutes + 15 minutes = 20 minutes. In all, Amaya spent 100 minutes + 20 minutes = 120 minutes watching the movie. The answer: 120.
