--------------------------------------------
The rate of the first pump is = 80 liters per minute.
The rate of the second pump is = 240 liters per minute.
When both pumps work simultaneously, their total rate is 80 + 240 = 320 liters per minute.
Hence, it will take = minutes = 3 minutes 45 seconds for both pumps to empty the tank, if they work simultaneously.
