Question

Water is pouring into a reservoir @ 60 litres per minute if the volume of the reserve is 108 metre cube find the number of hours it will take to fill the reservation

Answer 1

Answer:

Step-by-step explanation:

Given :-

Volume of reservoir = 108 m³

Amount of water poured in 1 minute = 60 litres

To Find :-

Number of hours to fill the reservoir.

Solution :-

⇒ Capacity of the reservoir = 108 × 1000

⇒ Capacity of the reservoir = 108000 letres

Amount of water poured in 1 minute = 60 × 60 litres

Number of hours to fill the reservoir = $\sf \frac{108000}{60\times60}$

Number of hours to fill the reservoir = 30 hours

Hence, the required number of hours will be 30 hours.

Answer 2

AnswEr :

• Volume of Reservoir = 108 m³
• Rate of Water Pouring = 60 l/min
• Find the Number of Hours to fill the reservation.

◗ Rate = 60 litre /minute

◗ Volume of Reservoir = 108 m³

• we will change volume into litre.

⇝ 108 m³

⇝ 108 × 1000 litre [ 1m³ = 1000 l ]

⇝ 108000 litre

_________________________________

• According to the Question Now :

⇒ Time Taken = Volume / Rate of Flow

⇒ Time Taken = 108000 / 60

⇒ Time Taken = 1800 minutes

• we will change into hour now

⇒ Time Taken = 1800 / 60 hour

⇒ Time Taken = 30 Hour

∴ It will take 30 hour to fill completely.
