Flynn watches 30 minutes of tv every night during the weekdays. On the weekends, she watches an additional 2 hours of TV in total. How many hours of tv does she watch in 52 weeks? Give the rationale and then the answer.
Let's think step by step. She watches 30 minutes of tv per night, 5 days a week so that's 30 * 5 = 150 minutes of tv. She watches 2 hours of tv on the weekends and 60 minutes are in 1 hour so that's 2 * 60 = 120 minutes of tv. All total she watches 150 + 120 = 270 minutes of tv per week. There are 52 weeks in a year and she watches 270 minutes per week so that's 52 * 270 = 14,040 minutes of tv per year. She watches 14,040 minutes of tv and 60 minutes are in an hour so she watches 14040 / 60 = 234 hours.. The answer is: 234.

On national lipstick day, half of the students who attended class wore colored lipstick. Of those students who wore lipstick, one quarter wore red lipstick. There were one-fifth as many students wearing blue lipstick as were wearing red lipstick. If 200 students attended school that day, how many wore blue lipstick? Give the rationale and then the answer.
Let's think step by step. Of 200 students who attended class, half wore colored lipstick, or 200 / 2 = 100 students wore colored lipstick. Of those students who wore lipstick, one quarter wore red lipstick, or 100 / 4 = 25 students wore red lipstick. Since there were one - fifth as many students wearing blue lipstick as were wearing red lipstick, then 25 / 5 = 5 students wore blue lipstick.. The answer is: 5.

During one hour, Tom can read 12 pages of a book. How many pages would he be able to read during 2 hours if he could increase his reading speed by a factor of 3? Give the rationale and then the answer.
Let's think step by step. If Tom could triple his reading speed, he could read 12 * 3 = 36 pages of a book in one hour. Therefore, during two hours he could read 36 * 2 = 72 pages.. The answer is: 72.
