Question

9. Water is pouring into a reservoir at the rate of 60 litres per minute. If the volume of the reservoir is 108 m², find the number of hours it will take to fill the reservoir.
please step everything and why.​

Answer 1

$\huge \sf {\orange {\underline {\red{\underline {❥Answer࿐ }}}}}$

Rate of flow of water = 60 litres/minute

Volume of the tank = 108 m3

1 m3 = 1000 litres

108 m3= 108000 litres

Time taken to fill the complete tank

= 108000/60 = 1800 minutes = 1800/60 hours = 30 hours

The tank will be filled completely in

30 hours.

Answer 2

Answer:

30 hours

Step-by-step explanation:

Volume of reservoir = 108m^3

                                      108 *1000

                                         108000l

Time taken to pour 60 l = 1min

""""""""""""""""""""""""      1l = 1/60 min

""""""""""""""""""""""" 108000l = 108000 * 1/60

                                              = 1800 min

                                               = 30 hrs
