Question: Nicole has three older sisters. After each one outgrows their clothes, they give them to Nicole. They have all outgrown their clothes and have given them all to Nicole. Nicole started with 10 pieces of clothing. Her first older sister had half as many clothes as Nicole. The next oldest sister had 2 more pieces of clothing than Nicole. The oldest had the average of what her three younger sisters had. How many pieces of clothing does Nicole end up with?
Answer: The first sister has 5 pieces of clothing because 10 / 2 = 5. The next sister had 12 pieces of clothing because 10 + 2 = 12. The three youngest sisters combined have 27 pieces because 10 + 5 + 12 = 27. The oldest has 9 pieces because 27 / 3 = 9. Nicole ends up with 36 pieces of clothing because 10 + 5 + 12 + 9 = 36. The answer is 36.
[Question]A fan can create an airflow of 10 liters per second. If the fan works for 10 minutes each day, calculate the amount of airflow it will create in one week.
[Answer]If the fan works for 10 minutes each day, in a week with 7 days, it will have worked for 10 * 7 = 70 minutes. Since a minute has 60 seconds, the total time in seconds that the fan will have worked in one week is 70 * 60 = 4200 seconds. Since the fan can create an airflow of 10 liters per second, in 4200 seconds, it will create an airflow of 4200 * 10 = 42000 liters. The answer is 42000.
Q: Over the past five years, on July 4th, the high temperature for Washington, DC has been: 90 degrees in 2020, 90 degrees in 2019, 90 degrees in 2018, 79 degrees in 2017 and 71 degrees in 2016. What is the average temperature for July 4th in Washington, DC over the past 5 years?
A: Over the past five years, the sum of the temperatures was 90 + 90 + 90 + 79 + 71 = 420. To find the average temperature you divide the total temperature (420) by 5, so 420 / 5 = 84 degrees. The answer is 84.
Question: A farmer is growing corn. For every 4 seeds he plants, he gets one ear of corn, that he can sell for $.1. It costs $.5 for a bag with 100 seeds. If he makes $40 in profit, how many ears did he sell?
Answer: A single seed costs $.005 because .5 / 100 = .005. It costs $.02 cents to grow an ear of corn because .005 x 4 = .02. On each ear of corn he makes $.098 profit because .1 - .02 = .08. He sold 500 ears because 40 / .08 = 500. The answer is 500.
[Question]Rob planned on spending three hours reading in preparation for his literature exam. If he ends up spending only three-quarters of this time reading, and he reads a page every fifteen minutes, how many pages did he read in this time?
[Answer]1 hour is 60 minutes so 3 hours is 3 * 60 = 180 minutes. Three - quarters of 180 minutes is (3 / 4) * 180 = 135 minutes. He spends 15 minutes on 1 page so he will spend 135 minutes on 135 / 15 = 9 pages. The answer is 9.
