Question 139313: Could someone please help with my homework problem. Can't figure out. The time required to empty a tank varies inversely as the rate of pumping. A pump can empty a tank in 90 minutes at the rate of 1200 L/min. How long will the pump take to empty the tank at 3000 L/min ? Thanks a lot.

How many L in the tank?
1200L*90=108,000L
108000/3000=36 min
