[Question]You walk twice as fast as Mr. Harris, and Mr. Harris took 2 hours to walk to the store. If your destination is 3 times further away than the store Mr. Harris walked to, how many hours will it take you to get there?
[Answer]First we find out how long it would take Mr. Harris to walk to your destination, which we find by multiplying his 2 hour walk by 3 since your destination is 3 times further away, meaning it would take him 2 * 3 = 6 hours. Since you walk twice as fast, it would take you half the time. Half of 6, 6 / 2 = 3 hours in total. The answer is 3.
Q: Jonah bought 6 pineapples for $3 each. Each pineapple could be cut into 12 pineapple rings. He sold 4 pineapple rings for $5 each. How much profit did Jonah make?
A: Jonah spent 6 x $3 = $18. He made a total of 6 x 12 = 72 pineapple rings. He sold 72 / 4 = 18 sets of pineapple rings. He made 18 x $5 = $90. His profit was $90 - $18 = $72. The answer is 72.
Question: Isabella is twice as old as Antonio. In 18 months, she will be 10 years old. How many months old is Antonio?
Answer: First, we determine that Isabella will be 10 * 12 = 120 months old at age 10, to find a number to compare her age to Antonio's with. Then we subtract the 18 months from the total of 120 months to find 120 - 18 = 102 months, which is the age Isabella is currently. Since at 102 months old Isabella is twice as old as Antonio, we take 102 / 2 = 51 months as Antonio's age. The answer is 51.
[Question]Trey has 7 times as many turtles as Kris. Kris has 1/4 as many turtles as Kristen has. How many more turtles does Trey have than Kristen, if Kristen has 12?

Q: Janet's grades for her first semester of college were 90, 80, 70, and 100. If her semester 2 average was 82 percent, how much higher was her semester 1 average compared to her semester 2 average?
A: First add all Janet's grade for the first semester of college: 90 + 80 + 70 + 100 = 340. Then divide that number by 4 to find her average grade: 340 / 4 = 85. Then subtract her semester 2 average to find the difference: 85 - 82 = 3. The answer is 3.
Question: Beckett is 12 and is three years younger than Olaf, while Shannen is two years younger than Olaf. If Jack is five more than twice as old as Shannen, what is the sum of the ages of all 4 people?
Answer:
Olaf is 12 years + 3 years = 15 years old. Shannen is 15 years old - 2 years = 13 years old. Jack is 5 years + (2 * 13 years) = 31 years old. The sum of all of their ages is 12 + 15 + 13 + 31 = 71 years old. The answer is 71.
