[Question]: Carla went to the zoo and counted 12 zebras in their enclosure. She then visited the camels and learned that there were only half as many camels as there were zebras. Next, she visited the monkeys and counted 4 times the number of monkeys as camels. Finally, she saw some giraffes and counted only 2 giraffes. How many more monkeys than giraffes did Carla see?
[Answer]: There were 12 zebras / 2 zebras / camel = 6 camels at the zoo. There were 4 monkeys / camel x 6 camels = 24 monkeys at the zoo. Therefore, Carla saw 24 monkeys - 2 giraffes = 22 more monkeys than giraffes.
So the answer is 22.

[Question]: The time Juan takes to grab his lunch from his office and back is half the time he takes to read a book. If he has a 4000-page book, how many pages does he read in an hour if he takes 4 hours to move from his office to grab lunch?
[Answer]: If Juan takes 4 hours to move from his office to grab lunch, moving from his office and back takes 2 * 4 = 8 hours. The time Juan takes to grab his lunch from his office and back is half the time he takes to read a book, meaning he reads a book in 8 * 2 = 16 hours. If he has a 4000 - page book, he will read 4000 / 16 = 250 pages in an hour.
So the answer is 250.
