8. Water is pouring into a cubiodal reservoir at the rate of 60 litres per
minute. If the volume of reservoir is 108 m, find the number of hours it
will take to fill the reservoir.​

Answer 1

Step-by-step explanation:

Converting the volume of water flowing per minute into m^3(metre cube/cubic metre):- Speed of water is 60L/min

=60÷1000m^3/min

=0.06m^3/min

Volume=108m^3

Therefore, time will be taken to fill the reservoir ==

VOLUME/SPEED=108/0.06 min

=10800/6 min

=1800min

=1800/60 hours

=30 hours

Answer 2

Step-by-step explanation:

First of all change the metre cube into litres

1m^3=1000L

108m^3=108000L

108000/60=1800 mins

So in 1800 mins the reservoir can fill

1800/60=30 hrs
