Question 276855
The time t required to empty a tank varies inversely as the rate r of pumping.  If a pump can empty a tank in 45 mins at the rate of 600kL/ min, how long will it take the pump to empty the same tank at the rate of 1000kL/min?

600 kl it empties in 45 minutes

1000 kl it will take less time

600/1000 * 45 = 27 mis.
