The kids collected 29 + 17 + 8 = 54 shells. If they distribute the shells evenly between 2 friends, 54 / 2 = 27 shells for each friend.
The answer: 27
Reverse engineering the question: Jillian, Savannah, and Clayton were collecting shells on the beach. Jillian collected 29, Savannah collected 17, and Clayton collected 8. They decided that they wanted to give the shells to two of their friends who had just arrived. They put their shells together and distributed them evenly to each friend. How many shells did each friend get?


Reasoning and answer: Let H = distance Hiro walked. 4H - 10 = distance Rajesh walked. H + 4H - 10 = 25. 5H - 10 = 25. 5H = 35. Hiro walked 7 km so Rajesh walked 4(7) - 10 = 18 km. Rajesh walked 18 kilometers.
The answer: 18
What was the question?
Question: Rajesh walked 10 kilometers less than 4 times the distance that Hiro walked. Together they walked 25 kilometers. How many kilometers did Rajesh walk?


Rick has one less than three stripes, or 3 - 1 = 2 stripes on each tennis shoe. Hortense has double the 3 stripes that Olga has, or a total of 3 * 2 = 6 stripes per shoe. Since each of them has two tennis shoes per pair, then the total number of stripes on all of their shoes is 2 * (3 + 2 + 6) = 22 stripes.
The answer: 22
Reverse engineering the question: Olga has three stripes on the side of each of her tennis shoes. Rick has one less stripe per shoe than does Olga. But Hortense has double the number of stripes on her tennis shoes as does Olga. In total, what is the combined number of stripes on all of their pairs of tennis shoes?


Reasoning and answer: She hiked 24 miles. She spent 6 hours hiking. Her average pace was 24 / 6 = 4 mph.
The answer: 4
What was the question?
Question: Arlene hiked 24 miles on Saturday, carrying a 60-pound backpack. She is exactly 5 feet tall. She spent 6 hours hiking. The temperature during the day was 60 degrees Fahrenheit. What was Arlene's average hiking pace, in miles per hour?


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?


To make the pizza, Kimber half as many teaspoons of salt as the number of cups of flour, meaning she needs 1 / 2 * 16 = 8 teaspoons of salt. The total number of cups of flour and teaspoons of salt she needs is 8 + 16 = 24. She also needs 10 cups of water, which means the total number of cups of water and flour and teaspoons of salt she needs is 24 + 10 = 34.
The answer: 34
Reverse engineering the question:
To make pizza, together with other ingredients, Kimber needs 10 cups of water, 16 cups of flour, and 1/2 times as many teaspoons of salt as the number of cups of flour. Calculate the combined total number of cups of water, flour, and teaspoons of salt that she needs to make the pizza.
