The dog runs .4 miles per minute because 24 / 60 = .4. The rabbit runs .25 miles per minute because 15 / 60 = .25. We know that .4(Number of Minutes) = .25(Number of Minutes) + .6. Therefore .15(Number of Minutes) = .6. Therefore (Number of Minutes) = 4.
The answer: 4
Reverse engineering the question: Erik's dog can run 24 miles per hour. It is chasing a rabbit that can run 15 miles per hour. The rabbit has a head start of .6 miles. How many minutes does it take for the dog to catch up to the rabbit?
Reasoning and answer: Since there are 60 minutes in 1 hour, then 1.3 hours is equal to 1.3 x 60 = 78 minutes. Thus, Samuel is 78 30 = 48 minutes faster than Sarah.
The answer: 48
What was the question?
Question: Samuel took 30 minutes to finish his homework while Sarah took 1.3 hours to finish it. How many minutes faster did Samuel finish his homework than Sarah?
The number of cows and foxes in the yacht is 20 + 15 = 35. Mr. Bodhi also has three times as many zebras as foxes in the yacht, equal to 3 * 15 = 45 zebras. The number of animals in the yacht so far is 35 + 45 = 80. To balance the yacht, Mr. Bodhi needs to add 100 - 80 = 20 sheep.
The answer: 20
Reverse engineering the question: Mr. Bodhi is transporting some animals using a yacht across a river. He has 20 cows, 15 foxes and three times as many zebras as foxes. To balance the yacht to ensure a smooth sail across the river, the total number of animals in the yacht needs to be 100. If he decides to add sheep to the yacht to make the yacht sail-worthy, how many sheep did he add to the yacht?
Reasoning and answer: In the morning, the store gives away 19 bikes * 2 bike clamps = 38 bike clamps. In the afternoon, they give away 27 bikes * 2 bike clamps = 54 bike clamps. So in total, the store has given away 38 + 54 = 92 bike clamps.
The answer: 92

Question: A bicycle store is running a promotion. Every time a customer buys a bicycle, they will receive 2 bike clamps free with it. If the store sells 19 bikes in the morning and 27 bikes in the afternoon, how many bike clamps has the store given to customers?
To find the number of total bike rides, we must first determine how many times John rode his bike. We do this by performing 17 * 2 = 34 times for John. Since John's mother rode 10 times more than John did, we find her total by performing 34 + 10 = 44 times. For all three people put together then, we perform 44 + 34 + 17 = 95 times in total.
The answer: 95
Reverse engineering the question: If Billy rode his bike 17 times, John rode his bike twice as many times, and their mother rode her bike 10 times more than John, how many times did they ride their bikes in total?
Claire's age now is 20 - 2 = 18 years old. Being 6 years older than Claire, Jessica is 18 + 6 = 24 years old.
The answer: 24
Reverse engineering the question:
Jessica is six years older than Claire. In two years, Claire will be 20 years old. How old is Jessica now?
