To get to the library, Jill spends 12 minutes waiting for her first bus, 30 minutes riding on her first bus, and half the combined wait and trip time on her second bus. How many minutes does her second bus ride take?
Let's think: First add the time spent waiting for the first bus to the time spent on it: 12 minutes + 30 minutes = 42 minutes. Then divide that time by 2 to find the time she spends on the second bus: 42 minutes / 2 = 21 minutes.. The answer is: 21.

Mrs. Lopez and her family are going to the movie theatre. Adult tickets are $11. Children’s tickets (ages 3-12) are $8. Senior citizen’s tickets (ages 60+) are $9. Mrs. Lopez needs to buy movie tickets for her husband, herself, her parents (ages 72 and 75), and her three children (ages 7, 10, 14). How much money does she need to buy everyone’s tickets?
Let's think: Mrs. Lopez needs to buy two adult tickets for $11 x 2 = $22. She needs to buy two senior citizen tickets for $9 x 2 = $18. She needs to buy three children’s tickets for $8 x 3 = $24. For everyone’s tickets, Mrs. Lopez needs to spend $22 + $18 + $24 = $64 for seven tickets.. The answer is: 64.

There's a Bobbit worm hiding in the bottom of James' aquarium. Every day it eats 2 fish. After two weeks, James adds 8 more fish to the aquarium. A week later, he discovers the Bobbit worm. If the aquarium had 60 fish to start with, how many does it have when James discovers the Bobbit worm?
Let's think: First find the total number of weeks the Bobbit worm preys on the fish: 2 weeks + 1 week = 3 weeks. Then multiply that number by the number of days per week: 3 weeks * 7 days / week = 21 days. Then multiply that number by the number of fish the worm eats per day to find how many fish it eats total: 21 days * 2 fish / day = 42 fish. Then add the number of fish James adds to the starting number of fish to find the ending number of fish: 60 fish + 8 fish = 68 fish. Then subtract the number of eaten fish to find the number of surviving fish: 68 fish - 42 fish = 26 fish.. The answer is: 26.
