Question: Polly the parakeet tweets all day long. When she is happy, she tweets 18 times per minute. When she is hungry, she tweets 4 times per minute. And when she watches herself in the mirror, she tweets 45 times per minute. During a time period where she is happy for 20 minutes, hungry for 20 minutes, and watches her reflection for 20 minutes, what is the total number of times she will tweet?
Answer: In 20 minutes, she happy tweets for 20 * 18 = 360 times. In 20 minutes, she hungry - tweets for 20 * 4 = 80 times. In 20 minutes, she tweets at her reflection 20 * 45 = 900 times. Altogether, she tweets 360 + 80 + 900 = 1340 times. The answer is 1340.

[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.
