Jim runs 5 miles a day for 30 days for a total of 5 * 30 = 150 miles. The next month Jim runs 10 miles a day for 10 * 30 = 300 miles. The last month Jim runs 20 miles a day for 20 * 30 = 600 a month. All together, Jim runs 150 + 300 + 600 = 1050 miles in three months.
The answer: 1050
Reverse engineering the question: Jim decides he wants to practice for a marathon coming up. He starts off by running 5 miles every day for 30 days straight. He then pushes himself to run 10 miles a day for the next 30 days. Finally, as marathon day gets closer Jim runs 20 miles a day for 30 days straight. How many miles does Jim run in total during the 90 days?


Reasoning and answer: If Charlize was 20 minutes late, each of her friends was 20 + 10 = 30 minutes late. The total time for which Charlize's friends were late was 4 * 30 = 120 minutes. Together with Charlize, the three friends were 120 + 20 = 140 minutes late.
The answer: 140
What was the question?
Question: At school today, Charlize was 20 minutes late. Four of her classmates were each ten minutes late than she was. What's the total time for which the five students were late?


The second competitor can eat 10 x 3 = 30 hotdogs per minute. The third competitor can eat 30 x 2 = 60 hot dogs per minute. Therefore, the third competitor can eat 60 x 5 = 300 hot dogs after 5 minutes.
The answer: 300
Reverse engineering the question: In a hotdog eating competition, the first competitor can eat 10 hot dogs per minute. The second competitor can eat 3 times more than the first competitor, while the third competitor can eat twice as much as the second competitor. How many hotdogs can the third competitor eat after 5 minutes?


Reasoning and answer: Jill made one and a half times as many coconut candles as almond candles, so she made 10 * 1 1 / 2 = 15 coconut candles. She made twice as many lavender candles as coconut candles, so she made 2 * 15 = 30 lavender candles.
The answer: 30
What was the question?
Question: Jill makes scented candles as a hobby. Her favorite scents are lavender, coconut, and almond, and she uses the same amount of each scent for every candle. This time, she made twice as many lavender candles as coconut candles, along with a batch of almond candles. She ran out of almond scent after making ten candles. If she had one and a half times as much coconut scent as almond scent and used all her coconut scent up too, how many lavender candles did she make?


There are 48 x 2 / 3 = 32 women on the bus. So, 48 - 32 = 16 are men. Out of the 16, 16 x 1 / 8 = 2 men are standing. Hence, 16 - 2 = 14 men are seated.
The answer: 14
Reverse engineering the question: There are 48 passengers on the bus. Two-thirds of the passengers are women and the rest are men. If one-eighth of the men are standing, how many men are seated?


Let’s first calculate what the apple trees produce: 30 trees * 150 kg / tree = 4500 kg. Then let's calculate what the peaches produce: 45 trees * 65 kg / tree = 2925 kg. We add these two masses: 4500 kg + 2925 kg = 7425 kg.
The answer: 7425
Reverse engineering the question:
Apple and peach trees are planted in the orchard of the Grange Poser farm. The orchard has 30 apple trees that each give 150 kg of apples and 45 peach trees that each produce an average of 65 kg of fruit. What is the total mass of fruit harvested in this orchard?
