[Question]Ned is an explosives specialist racing to deactivate a time bomb on the top floor of a building. The building has twenty flights of stairs to the top floor, and Ned can run up one flight of stairs in eleven seconds. The time bomb has 72 seconds left on the timer, and Ned has spent 165 seconds running up the stairs. How many seconds will Ned have to diffuse the bomb when he reaches it?
[Answer]Ned has gone up 165 / 11 = 15 flights of stairs. Thus, he has 20 - 15 = 5 flights of stairs left to run up. He will spend 5 * 11 = 55 seconds running up the remaining stairs to the bomb. Therefore, he will have 72 - 55 = 17 seconds to defuse the bomb. The answer is 17.
Q: John buys 1/2 gallon jugs of cold brew coffee every 4 days. How many cups of coffee does he drink a day?
A: He drinks 128 / 2 = 64 ounces of coffee every 4 days. That means he drinks 64 / 4 = 16 ounces of coffee a day. So he drinks 16 / 8 = 2 cups a day. The answer is 2.
Question: Tommy has 10 more sheets than Jimmy does. If Jimmy has 32 sheets, how many more sheets will Jimmy have than Tommy if his friend Ashton gives him 40 sheets.
Answer: If Jimmy has 32 sheets, and Tommy has 10 more sheets than Jimmy does, Tommy has 10 + 32 = 42 sheets. When Ashton gives Jimmy 40 sheets, his total number of sheets increases to 32 + 40 = 72. The number of sheets that Jimmy now have than Tommy is 72 - 42 = 30. The answer is 30.
[Question]Karen is packing her backpack for a long-distance hike. She packs 20 pounds of water, 10 pounds of food, and 20 pounds of gear. During her hike, she drinks 2 pounds of water per hour and eats 1/3rd the weight of food per hour as water per hour. How much weight is she carrying after six hours?
[Answer]First find the weight of food Karen eats every hour: 2 pounds * 1 / 3 = 2 / 3 pounds food. Then find the total amount of weight Karen's backpack loses per hour she hikes: 2 pounds water / hour + 2 / 3 pound food / hour = 8 / 3 pounds / hour. Multiply this by the number of hours she hikes to find the total amount of weight she loses: 8 / 3 pounds / hour * 6 hours = 16 pounds. Add the weight of all her items to find total starting weight: 20 pounds + 10 pounds + 20 pounds = 50 pounds. Then subtract the weight she loses from the starting weight to find the weight after 6 hours: 50 pounds - 16 pounds = 34 pounds. The answer is 34.
Q: Jack goes hunting 6 times a month. The hunting season lasts for 1 quarter of the year. He catches 2 deers each time he goes hunting and they weigh 600 pounds each. He keeps half the weight of deer a year. How much deer does he keep in pounds?
A: The hunting season last 12 / 4 = 3 months. So he goes hunting 3 * 6 = 18 times a year. That means he gets 18 * 2 = 36 deers per year. So he catches 36 * 600 = 21,600 pounds of deer a year. That means he keeps 21600 / 2 = 10,800 pounds of deer a year. The answer is 10800.
Question: Louise is hanging 30 of her pictures on the wall. She hangs some of them vertically, half of them horizontally, then hangs the remaining 5 pictures haphazardly. How many pictures did Louise hang vertically?
Answer:
There are 30 / 2 = 15 pictures hanging horizontally. So there is a total of 15 + 5 = 20 pictures hanging either horizontally or haphazardly. Therefore, there are 30 – 20 = 10 pictures hanging vertically. The answer is 10.
