The volume of a tank is 33 000 cm The tank is empty. The tank is filled at the rate of 0.22 litres a second. How many minutes will it take to fill the tank?

1 L = 1000 cm^3, so 0.22 L = 220 cm^3.  The tank fills at a rate of (220 cm^3/s)(60s/min) = 13200 cm^3/minute.

So the number of minutes to fill it is  

33000/13200 = 2.5
