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.
##Solution## If the fan works for 10 minutes each day, in a week with 7 days, it will have worked for 10*7 = <<10*7=70>>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 = <<70*60=4200>>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= <<4200*10=42000>>42000 liters.
