Water flows into a tank at rate of 3 litres per minute . a the tank fills completely in 450 seconds , what is the capacity of the tank in ml ? A hole is drilled in the bottom of the tank . Water flows out of the hole at a rate of 60ml per second. How long will the tank take to drain completely if the flow of water in continues at the same rate? ​

3 litres per minute

=> 3/60 litres per second

i.e. 1/20 litre per second

or, 50 ml per second

Hence, capacity is 50 x 450 = 22,500 ml

If water flows out at 60 ml per second and waters flows in at 50 ml per second we have a net loss of 10 ml per second

Hence, 22,500/10 => 2,250 seconds to drain empty

Step-by-step explanation:

3 litres per minute
