 <translate> 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. <yor> Bí afẹ́fẹ́ náà bá ń ṣiṣẹ́ fún ìṣẹ́jú mẹ́wàá lójúmọ́, láàárín ọ̀sẹ̀ kan tó ní ọjọ́ méje, yóò ti ṣiṣẹ́ fún ìṣẹ́jú mẹ́wàá * méje = àádọ́rin.
