Vivian is responsible for making sure her students get 2 15-minute recess breaks a day, a 30-minute lunch and another 20-minute recess break. How much time do her students spend outside of class? Let's answer step by step:
They get 2 15 minute breaks a day so that's 2 * 15 = 30 minutes. They get 30 minutes for lunch and 20 minutes for recess plus an additional 30 minutes of recess for a total of 30 + 20 + 30 = 80 minutes spent outside of class. The answer: 80.
