Each step Roger walks for 30 / 2000 = 0.015 minutes. To walk 10000 steps he'll take 0.015 * 10000 = 150.
The answer: 150
Reverse engineering the question: Roger uses his lunch break to walk the stairs in his office building. He can walk 2,000 steps in 30 minutes. If his daily goal is 10,000 steps, how many minutes will it take him to reach his goal?
Reasoning and answer: Each dog consumes 1.5 x 3 = 4.5 cups of food a day. In pounds, this is equal to 4.5 / 2.25 = 2. So both consume 2 x 2 = 4 pounds of food.
The answer: 4

Question: Tracy feeds each of her two dogs 1.5 cups of food per meal. She feeds her dogs thrice a day. How many pounds of food do her two dogs consume if 1 pound is equal to 2.25 cups?
First find how many more hawks than crows there are: 60% * 30 crows = 18 crows. Then add that number to the number of crows to find the total number of hawks: 18 crows + 30 crows = 48 crows. Then add the number of crows to the number of hawks to find the total number of birds: 48 crows + 30 crows = 78 crows.
The answer: 78
Reverse engineering the question: Janet counts 30 crows on the powerlines and 60% more hawks than crows. How many birds does she count total?
Reasoning and answer: Oliver used 1 / 3 x 135 = 45 stickers. So, there were 135 - 45 = 90 stickers remaining. His friend received 2 / 5 x 90 = 36 stickers. Therefore, Oliver kept 90 - 36 = 54 stickers.
The answer: 54
What was the question?
Question: Oliver had 135 stickers. He used 1/3 of his stickers, gave 2/5 of the remaining to his friend, and kept the remaining stickers. How many stickers did he keep?
If there are 80 fish in total, then there are 80 fish / 2 = 40 blue fish. The orange fish count is 15 less than blue, so it's 40 fish - 15 fish = 25 fish. Olaf has then 80 fish - 25 fish - 40 fish = 15 green fish.
The answer: 15
Reverse engineering the question: Olaf has an aquarium. He has fish in 3 different colors: orange, green, and blue. Blue fish make up half of all the fish in the aquarium. There are 15 fewer orange fish than blue fish. How many green fish are there when the total number of fish in the aquarium is 80?
If Kristoff has 85 stickers, Riku has 25 * 85 stickers = 2125 more stickers. The total number of stickers Riku has is 2125 stickers + 85 stickers = 2210 stickers.
The answer: 2210
Reverse engineering the question:
Riku has 25 times more stickers than Kristoff. If Kristoff has 85 stickers, how many stickers does Riku have?
