Question

water is pouring into a Reservoir at the rate of the 60 litres per minute. if the volume of the reservior is 180 m3, find the number of the hours it will take to fill the reservoir

Answer 1

Here, the point of this question is to apply volume-to-capacity (I don't know what it's actually called, sorry...) conversion formula.

As 1 m3 = 1000 litres

Then 180 m3 = (180 x 1000) litres = 180,000 litres

Now, water is pouring at the rate of 60 litres/min

=> It is pouring at the rate of 1 litre/sec

Therefore, the total time taken to fill the reservoir

= 180,000 secs

= 3000 mins

= 50 hrs

Hence, it will take 50 hours to fill the reservoir.

Answer 2

This is solution of this sum
