Q: 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?
A: 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 is 80.
Question: 3 years ago James turned 27. In 5 years Matt will be twice James age. How old is Matt now?
Answer: James is now 27 + 3 = 30 years old. In 5 years James will be 30 + 5 = 35 years old. So in 5 years Matt will be 35 * 2 = 70 years old. That means Matt is now 70 - 5 = 65 years old. The answer is 65.
[Question]As a child, Bobby was able to jump rope 30 times per minute. Now that he is an adult, he can jump 1 jump per second. How many more jumps than when he was a child is Bobby able to jump now that he is an adult?

Q: In a certain school, 2/3 of the male students like to play basketball, but only 1/5 of the female students like to play basketball. What percent of the population of the school do not like to play basketball if the ratio of the male to female students is 3:2 and there are 1000 students?
A: The students are divided into 3 + 2 = 5 parts where 3 parts are for males and 2 parts are for females. Each part represents 1000 / 5 = 200 students. So, there are 3 x 200 = 600 males. And there are 2 x 200 = 400 females. Hence, 600 x 2 / 3 = 400 males play basketball. And 400 x 1 / 5 = 80 females play basketball. A total of 400 + 80 = 480 students play basketball. Therefore, 1000 - 480 = 520 do not like to play basketball. The percentage of the school that do not like to play basketball is 520 / 1000 * 100 = 52. The answer is 52.
Question: Tony can run a mile twice as fast as Tina, who with a time of 6 minutes is one-third as fast a runner as Tom. What are all three of their mile times when added together?
Answer: Since someone running twice as fast a mile as another person would mean they complete the mile in half as much time, this means Tony would run a mile in 6 / 2 = 3 minutes since Tina's time was 6 minutes. Since Tom is three times as fast as Tina, for the same reasons as above this means his time is 6 / 3 = 2 minutes. Altogether then, the total time for all three is then 6 + 3 + 2 = 11 minutes. The answer is 11.
Q: Reina has three times the number of counters and four times the number of marbles as Kevin. If Kevin has 40 counters and 50 marbles, calculate the number of counters and marbles that Reina has?
A:
If Kevin has 40 counters, and Reina has three, the number of counters Kevin has, Reina has 3 * 40 = 120 counters. Reina also has four times the number of marbles that Kevin has, meaning he has 4 * 50 = 200 marbles. In total, Reina has 120 counters + 200 marbles = 320 items. The answer is 320.
