A motor pumps water from a well into a tank at the rate of 3000 c.c./sec while another outlet pumps water out of the tank at the rate of 1800 c.c./sec. If the capacity of the tank is `72xx10^(6)`c.c., then find the time required for the tank to get filled if both the motor and outlet are in operation (in minutes).
