using a constant flow of water, it usually takes three hours to fill the trough. However it now has a hole in it. The trough is now losing water at a rate of one litre every minute.

How long will it take to fill the trough from empty.

Give your answer in Hours, minutes, seconds.

( the volume of the trough is 2.646 M3 which is 2646 litres)

thanks!!!!!
