The tank normally takes 6hrs to fill but due to leak it takes 7 hrs to fill.
Suppose we have a 42cc tank.
Rate at which it would normally fill = 42/6 = 7cc/h
Rate at which it would normally with the leak = 42/7 = 6cc/h

So due to leak we have a decrease of 1cc/h.
At this rate time that the leak would take to empty this 42cc tank = 42cc / 1cc/hr = 42 hrs
