Solution :-
~Here, we're given the volume of the reservoir and the speed of water flowing in it. Firstly we need to convert the volume given to us in litres as the speed given to us is 70 liters per min . Then , we can easily find the time taken .
Conversion of volume :-
→ 1 m³ = 1000 L
→ 126 m³ = 126 × 1000
= 126000 L
Now,
By unitary method :-
Conversion into hours :-
