[Question]Sofia and her mother go to the grocery store and buys 10kgs of oranges to be used in their home for the week. While at the store, Sofia's father calls and says they're to add 5 more kgs since their neighbor also wanted some supplies. When they reach home, they estimated that for the next coming two weeks they'll have to buy twice as many oranges each week for the supplies to be enough. What the total quantity of oranges they would have bought after the three weeks.
[Answer]For the first week, they bought 10 + 5 = 15kgs. For the next week, they bought twice the quantity of oranges which is 2 * 15 = 30kgs. For the next two weeks, the total quantity of oranges bought is 30 * 2 = 60 kgs. The total quantity for the three weeks is 60 + 15 = 75 kgs. The answer is 75.
Q: Bethany is working at the front desk at Joe's Gym. There were some people lifting weights when she started her shift. Then 5 more people came in and started running on the treadmill and 2 people left. There are now 19 people in the gym. How many people were lifting weights at the start of Bethany's shift?
A: We know that 5 people came in and 2 people left after Bethany's shift started, so there was a net change of 5 2 = 3 people. If there are 19 people now in the gym and that is 3 more than when Bethany's shift started, we know there were 19 3 = 16 people lifting weights at the start of her shift. The answer is 16.
Question: Kevin's fish tank was leaking slowly at a rate of 1.5 ounces per hour. He planned to go to the fish tank store later that day to get a new tank, but it may be as long as 12 hours before he can return home with the new tank. Therefore, to collect the leaking fluid over that time, he placed a bucket underneath the tank that could hold twice the amount of fluid that would leak over 12 hours. What size bucket, in ounces, did he use?
Answer: Over 12 hours, a leak of 1.5 ounces per hour for 12 hours would generate 1.5 * 12 = 18 ounces. A bucket that can hold twice the volume leaked is 18 * 2 = 36 ounces. The answer is 36.
[Question]Cortney is downloading some files to her computer. Her internet speed is 2 megabits per minute. If she can download the files one at a time and the files she is downloading have the size of 80 megabits, 90 megabits, and 70 megabits. How many hours will it take for her to download all of it?
[Answer]The first file will take 80 / 2 = 40 minutes to download. The second file will take 90 / 2 = 45 minutes to download. And the third file will take 70 / 2 = 35 minutes to download. So, it will take 40 + 45 + 35 = 120 minutes for all the files to download. Therefore, the total hours she will have to spend to download all the files is 120 / 60 = 2 hours. The answer is 2.
Q: Chad is measuring the size of different countries. He sees that Canada is 1.5 times bigger than the United States and Russia is 1/3 bigger than Canada. How many times bigger is Russia than the United States?

Question: While Paul watches movies, he runs on his treadmill. He can run a mile in 12 minutes. He watches two movies, which are an average length of 1.5 hours. How many miles does he run?
Answer:
He runs for 3 hours because 2 x 1.5 = 3. He runs for 180 minutes because 3 x 60 = 180. He runs 15 miles because 180 / 12 = 15. The answer is 15.
