Question

10) Water is pouring into a reservoir at the rate of 72 litres per minute. If the volume of the reservoir is 108 cubic metre, find the number of hours it will take to fill the reservoir.

Answer 1

Answer:

It will take 25 hours to fill the reservoir.

Step-by-step explanation:

• Rate of water flow = 72 litres/minute

• Volume of reservoir = 108 m³

1 m³ = 1000 litres

⇒ 108 m³ = 108,000 litres

__________________________________________________________

Time taken to fill reservoir = (Volume of reservoir) / (Rate of water flow)

⇒ (108000 litres) / (72 litres/minute)

⇒ 1500 minutes

__________________________________________________________

To convert minutes to hours,

1 minute = 1/60 hour

⇒ 1500 minutes = 1500/60 hours

⇒ 25 hours
