Question: Carol spends five hours filling up her pool. During the first hour, the pool fills at a rate of 8 gallons of water per hour. For the next two hours, the pool fills at 10 gallons of water per hour. For the fourth hour, the pool fills at a rate of 14 gallons of water per hour. During the fifth hour, the pool develops a leak and loses 8 gallons of water. At the end of five hours, how many gallons of water are still left in the pool?
Answer: Step-by-step reasoning process: 8 gallons of water added during the first hour. 10 gallons of water added during the second hour. 10 gallons of water added during the third hour. 14 gallons of water added during the fourth hour. The total gallons of water added by the fourth hour is 8 + 10 + 10 + 14 = 42. The number of gallons in the pool after losing 8 gallons in the fifth hour is 42 - 8 = 34.
So the answer is 34.

Question: In a certain forest, there are 4 species of trees: oak, pine, spruce, and birch. There is a total of 4000 trees in the forest. Spruces make up 10% of all the trees, and pines 13%. There are as many oaks as spruces and pines put together. How many birches are there in the forest?
Answer: Step-by-step reasoning process: There are 10 / 100 * 4000 = 400 spruces in the forest. There are 13 / 100 * 4000 = 520 pines in the forest. There are as many oaks as pines and spruces together, so there are 400 + 520 = 920 oaks. Therefore there are 4000 - 920 - 520 - 400 = 2160 birches.
So the answer is 2160.

Question: Joy fosters dogs. The mom foster dog eats 1.5 cups of food, three times a day. The puppies each eat 1/2 cup of food, twice a day. There are 5 puppies. How much food will Joy need for the next 6 days?
Answer: Step-by-step reasoning process: The mom dog eats 1.5 cups of food * 3 = 4.5 cups per day. For 6 days the mom dog will need 6 * 4.5 cups = 27 cups of food. The puppies eat 1 / 2 cup of food * 2 = 1 cup per day. There are 5 puppies * 1 cup = 5 cups per day for the puppies. For the 6 days, the puppies will need 5 cups * 6 = 30 cups of food. Combined the dogs will need 27 cups + 30 cups = 57 cups.
So the answer is 57.

Question: Mark wants to set the record for most consecutive ropes jumped. The record is 54,000. He can jump 3 times a second. How many hours would he need to jump rope?
Answer:
Step-by-step reasoning process: He can jump 3 * 60 = 180 times per minute. So he can jump 180 * 60 = 10,800 per hour. So it would take him 54,000 / 10,800 = 5 hours.
So the answer is 5.
