Question: Mike began to train to play basketball every day for a tournament. One day he plays a maximum of 2 hours. After a week of training, he increased the maximum time to 3 hours. How many hours did Mike train during the first two weeks?
Answer: One week is 7 days, so for one week, Mike trained for 7 * 2 = 14 hours. The second week he began to train for 3 hours a day, so he trained for 7 * 3 = 21 hours. That means Mike in total trained for 21 + 14 = 35 hours. The answer is 35.
[Question]Steven's teacher sends the class an assignment to collect 60 different fruit seeds. Apples average 6 seeds, pears average 2 seeds, and grapes average 3 seeds. Steven has set aside 4 apples, 3 pears, and 9 grapes to extract their seeds. How many more seeds does he need to fulfill his assignment?
[Answer]With 4 apples, Steven will collect 4 apples * 6 seeds / apple = 24 seeds. With 3 pears, Steven will collect 3 pears * 2 seeds / pear = 6 seeds. With 9 grapes, Steven will collect 9 grapes * 3 seeds / grape = 27 seeds. In total, Steven will collect 24 seeds + 6 seeds + 27 seeds = 57 seeds. To collect 60 seeds he needs 60 seeds - 57 seeds = 3 more seeds. The answer is 3.
Q: Jackson is making pancakes with three ingredients: flour, milk and eggs. 20% of the bottles of milk are spoiled and the rest are fresh. 60% of the eggs are rotten. 1/4 of the cannisters of flour have weevils in them. If Jackson picks a bottle of milk, an egg and a canister of flour at random, what are the odds all three ingredients will be good?
A: First find the percentage of milk bottles that are fresh: 100% - 20% = 80%. Then find the percentage of the eggs that aren't rotten: 100% - 60% = 40%. Then find the fraction of the flour canisters that don't have weevils: 1 - 1 / 4 = 3 / 4. Divide the numerator of this fraction by the denominator and multiply by 100% to convert from a fraction to a percent: 3 / 4 * 100% = 75%. Then multiply the probability that each ingredient is good to find the probability they all are: 75% * 80% * 40% = 24%. The answer is 24.
Question: Maria gave a third of her money to her friend Isha, half of what she gave to Florence. If Florence received three times as much money as Maria's cousin Rene, and Rene received $300, how much money did Maria give her three friends?
Answer: The total amount of money that Florence received is 3 * 300 = $900, three times as much money as Rene received. Maria gave Isha half the amount of money that Florence received, which is $900 / 2 = $450. Maria gave her friends $450 + $900 + $300 = $1650. The answer is 1650.
[Question]Diana needs to bike 10 miles to get home. She can bike 3 mph for two hours before she gets tired, and she can bike 1 mph until she gets home. How long will it take Diana to get home?
[Answer]In the first part of her trip, Diana will cover 2 hours * 3 mph = 6 miles. In the second part of her trip, Diana will need to cover an additional 10 miles - 6 miles = 4 miles. To cover 4 miles * 1 mph = will take Diana 4 hours. Total biking time to get home for Diana will be 2 hours + 4 hours = 6 hours. The answer is 6.

If Anika is 30 now, in 15 years, she'll be 30 + 15 = 45 years old. At 30, Anika is 4 / 3 the age of Maddie, meaning Maddie is 4 / 3 * 30 = 40 years. In 15 years, Maddie will be 40 + 15 = 55 years old. Their total age in 15 years will be 55 + 45 = 100. Their average age in 15 years will be 100 / 2 = 50. The answer is 50.
