First find the total distance to the beach: 16 blocks * 1 / 8 mile / block = 2 miles. Then find how long in hours Jack has to get to the beach: 10 minutes / 60 minutes / hour = 1 / 6 hour. Then divide the distance Jack needs to cover by the time in hours he has to find how fast he needs to jog: 2 miles / 1 / 6 hour = 12 miles / hour.
The answer: 12
Reverse engineering the question: Jack bought an ice cream cone before jogging to the beach. If the ice cream cone will melt in 10 minutes, the beach is 16 blocks away, and each block is 1/8th of a mile, how fast does Jack need to jog (in miles per hour) to get to the beach before the ice cream melts?


Reasoning and answer: The total cost of cupcakes was 1.5 * 12 = $18. So they each paid 18 / 2 = $9.
The answer: 9

Question: John and his best friend Steve bought 12 cupcakes together. Each cupcake cost $1.50. If they split the costs evenly, how much did each person pay?


While in Bali, Palmer took 50 pictures in the first week and thus 2 * 50 photos = 100 photos in the second week. The total number of photos she took in Bali is 50 photos on the first week + 100 photos on the second week + 130 photos = 280 photos. When she adds the photos she from Bali to her album, Palmer has a total of 280 + 100 = 380 photos.
The answer: 380
Reverse engineering the question: Palmer loves taking photos and has an album of 100 photos under her bed to mark memories of places she's been. She recently went on a long trip to Bali. Palmer took 50 new pictures in the first week and twice that many in the second week. She was running out of space at the end of her trip and took only 80 new photos total across the third and fourth weeks. If she adds the pictures from Bali to her collection, how many total photos does Palmer have under her bed now?


Reasoning and answer: First, we need to determine which neighborhood is the better choice by comparing the number of boxes sold. A has 10 houses which will buy 2 boxes each, meaning A will give Jenny 10 * 2 = 20 box sales. Neighborhood B has 5 homes which will each buy 5 boxes, meaning she will sell 5 * 5 = 25 boxes by going to that neighborhood. Since 25>20, this means Jenny should choose neighborhood B. Since Jenny earns $2 per box sold, this means she will earn 25 * 2 = 50 dollars by choosing neighborhood B.
The answer: 50
What was the question?
Question: Jenny wants to sell some girl scout cookies and has the choice of two neighborhoods to visit. Neighborhood A has 10 homes which each will buy 2 boxes of cookies. Neighborhood B has 5 homes, each of which will buy 5 boxes of cookies. Assuming each box of cookies costs $2, how much will Jenny make at the better choice of the two neighborhoods?


A century has 100 years, and if Gideon has as many marbles as the number of years in a century, he has 100 marbles. If he gives 3 / 4 of the marbles to his sister, he gives out 3 / 4 * 100 = 75 marbles. Gideon's total number of marbles remaining after giving 3 / 4 of the marbles to his sister is 100 - 75 = 25. When he multiplies the number of remaining marbles by 2, he gets his age five years from now, meaning he will be 25 * 2 = 50 years old five years from now. Currently, Gideon is 50 - 5 = 45 years old.
The answer: 45
Reverse engineering the question: The total number of years in a century is the same as the number of marbles Gideon has. If he gives 3/4 of the marbles to his sister and multiples the number of remaining marbles by 2, he gets his age five years from now. How old is Gideon now?


Carter is twice as tall as 24” dog so he is 2 * 24 = 48”. Betty is 12” shorter than Carter so Betty is 48 - 12 = 36” tall. 12" is the same as 1 foot so Betty is 36 / 12 = 3 feet tall.
The answer: 3
Reverse engineering the question:
Carter is twice as tall as his 24” tall dog. Betty is 12” shorter than Carter. How tall is Betty in feet?
