Question: On a normal day, Julia can run a mile in 10 minutes. However, today she decided to wear her new shoes to run. They were uncomfortable and slowed her mile down to 13 minutes. How much longer would it take Julia to run 5 miles in her new shoes than if she wore her old ones?
Answer: With her regular shoes, it should take 5 * 10 = 50 minutes to run five miles. If she wore her new shoes it would take 13 * 5 = 65 minutes to run five miles. 65 - 50 = 15 more minutes. The answer is 15.

Question: Josie and her family went on a safari and had an exciting time watching different animals grazing and playing together. She decided to count each animal she saw and calculated their total number. She counted 80 antelopes, 34 more rabbits than antelopes, 42 fewer hyenas than the total number of antelopes and rabbits combined, 50 more wild dogs than hyenas, and the number of leopards was half the number of rabbits. What the total number of animals that Josie counted?
Answer: The number of rabbits was 80 + 34 = 114. The total number of rabbits and antelopes is 114 + 80 = 194. The number of hyenas was 42 fewer than the combined number of antelopes and rabbits, which is 194 - 42 = 152. The number of wild dogs was 50 more than the number of hyenas, that is 152 + 50 = 202. The number of leopards is 1 / 2 * 114 = 57. The total number of animals Josie saw is 57 + 202 + 152 + 114 + 80 = 605. The answer is 605.

Question: Alannah, Beatrix, and Queen are preparing for the new school year and have been given books by their parents. Alannah has 20 more books than Beatrix. Queen has 1/5 times more books than Alannah. If Beatrix has 30 books, how many books do the three have together?
Answer: If Beatrix has 30 books, Alannah has 30 books + 20 books = 50 books. Queen has 1 / 5 * 50 books = 10 more books than Alannah. The total number of books Queen has is 50 books + 10 books = 60 books. All three have 60 books + 50 books + 30 books = 140 books together. The answer is 140.
