Each session is 30 / 60 = .5 hours. So she spends .5 * 2 = 1 hour a day. So she spends 1 * 7 = 7 hours a week.
The answer: 7
Reverse engineering the question: James spends 30 minutes twice a day on meditation. How many hours a week does he spend meditating?


Reasoning and answer: The class needs to read 300 hours in a week because 299 + 1 = 300. The class needs to read 60 hours a day because 300 / 5 = 60. Each student needs to read 3 hours a day because 60 / 20 = 3.
The answer: 3

Question: The school is having a book-a-thon. The winning class gets a pizza party. The fifth grade has 20 students and one week to read as much as possible. The 6th grade already finished and read a total of 299 hours. How many hours does each student in 5th grade need to average per day to beat them by 1?


She will read 20 pages / 4 = 5 pages for English. She will read 16 pages / 4 = 4 pages for Science. She will read 8 pages / 4 = 2 pages for Civics. She will read 12 pages / 4 = 3 pages for Chinese. Melody will read a total of 5 pages + 4 pages + 2 pages + 3 pages = 14 pages tomorrow.
The answer: 14
Reverse engineering the question: Melody needs to read 20 pages for her English class, 16 pages for her Science class, 8 pages for her Civics, and 12 pages for Chinese class. She decided to read one-fourth of the number of pages for each class tomorrow. How many pages will she read tomorrow?


Reasoning and answer: Since 60 minutes equal 1 hour, in 2 hours, Eliza ironed blouses for 2 x 60 = 120 minutes. Eliza can iron 120 / 15 = 8 blouses. Since 60 minutes equal 1 hour, in 3 hours, Eliza ironed dresses for 3 x 60 = 180 minutes. Eliza can iron 180 / 20 = 9 dresses. In total, Eliza ironed 8 + 9 = 17 pieces of clothes.
The answer: 17
What was the question?
Question: Eliza can iron a blouse in 15 minutes and a dress in 20 minutes. If she spends 2 hours ironing blouses and 3 hours ironing dresses, how many pieces of clothes did she iron?


Josephine filled a total of 2 x 3 = 6 liters from the three containers with two liters each. She filled a total of 0.75 x 2 = 1.5 liters from the two containers with 0.75 liters each. She filled a total of 0.5 x 5 = 2.5 liters from the five containers with 0.5 liters each. Therefore, she sold a total of 6 + 1.5 + 2.5 = 10 liters of milk.
The answer: 10
Reverse engineering the question: On a Sunday morning, Josephine sold milk in the farm stall. The buyers brought their containers. She filled three containers with two liters each, two containers with 0.75 liters each, and five containers with 0.5 liters each. How many liters of milk did Josephine sell in total?


Twenty shirts amount to $10 x 20 = $200. The cost of each pair of jeans is $10 x 2 = $20. So 10 pairs of jeans amount to $20 x 10 = $200. Therefore, the store will earn $200 + $200 = $400 if all shirts and jeans are sold.
The answer: 400
Reverse engineering the question:
A clothing store sells 20 shirts and 10 pairs of jeans. A shirt costs $10 each and a pair of jeans costs twice as much. How much will the clothing store earn if all shirts and jeans are sold?
