In the first hour, it produces 60 / 6 = 10 pots. In the last hour, it produces 60 / 5 = 12 pots. 12 - 10 = 2 more pots are produced in the last hour.
The answer: 2
Reverse engineering the question: When the machine is cold, as it is in the first hour of production, it takes 6 minutes to produce each molded flower pot. Thereafter, once it is warm, it takes only 5 minutes to produce each pot. How many additional pots are produced in the last hour of the day, compared to the first?


Reasoning and answer: Hannah harvests a total of 5 * 30 = 150 strawberries. After giving her friends, Hannah is left with 150 - 20 = 130 strawberries. After some were stolen, Hannah is left with 130 - 30 = 100 strawberries.
The answer: 100
What was the question?
Question: Hannah harvests 5 strawberries daily for the next whole month of April, which has 30 days. If she gives away 20 strawberries to her friends and 30 strawberries are stolen, how many strawberries does she have by the end of April?


Alessia = 1.5 * 10 = 15 pounds. Alexei = 2.5 * 8 = 20 pounds. 15 + 20 = 35 pounds. Together they lost 35 pounds.
The answer: 35
Reverse engineering the question: Aleesia lost 1.5 pounds each week for 10 weeks. Alexei lost 2.5 pounds each week for 8 weeks. How many pounds did the two friends combine to lose?


Reasoning and answer: Ellie needs 2 wheels * 10ml of oil per wheel = 20ml of oil. To fix the rest of the bike as well, she needs 20 + 5 = 25ml of oil.
The answer: 25
What was the question?
Question: Ellie has found an old bicycle in a field and thinks it just needs some oil to work well again. She needs 10ml of oil to fix each wheel and will need another 5ml of oil to fix the rest of the bike. How much oil does she need in total to fix the bike?


The length of the highway that needs to be constructed is 650 – 200 = 450 miles. After the first day, there are still 450 – 50 = 400 miles that need to be constructed. On the second day, 50 miles * 3 = 150 miles are added to the highway. This means that 400 – 150 = 250 miles still need to be added to the highway.
The answer: 250
Reverse engineering the question: A highway is being extended from its current length of 200 miles up to 650 miles. 50 miles are built on the first day, and three times this amount are built on the second day. How many miles still need to be added to the highway to finish extending it?


Twice the width is 4 x 2 = 8 meters. The length of the rectangular flowerbed is 8 - 1 = 7 meters. Since the rectangular flower bed has 2 equal lengths, then it needs 7 x 2 = 14 meters of fence. The rectangular bed has also 2 equal widths, so it needs 4 x 2 = 8 meters of fence. Therefore, the rectangular flower bed needs a total of 14 + 8 = 22 meters of fence.
The answer: 22
Reverse engineering the question:
A rectangular flowerbed in the city park is 4 meters wide. Its length is 1 meter less than twice its width. The government wants to fence the flowerbed. How many meters of fence are needed?
