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. <hau> Idan fan yana aiki na mintina 10 a kowace rana, a cikin mako guda tare da kwanaki 7, zai yi aiki na mintina 10 * 7 = 70.
