Question

water is pouring into a reservoir at the rate of 60 litres per minute if the volume of reservoir is 108m 3 find the number of hours it will take to fill the reservoir

Answer 1

Given :
Rate of flowing of water into the reservoir is 60 litres per minute,
and volume of the reservoir is 108 cm³.

$\underline{Relationship }$
1 m³ = 1 ml
1 litre = 1000 cm³
1 m³ = 1000000 cm³ = 1000 litres

If,
1 m³ = 1000 litres
so,
capacity of reservoir = 108 × 1000 = 108000 litres

.

Water is being poured at rate of 60 litre per minute.

= (60 × 60) = 3600 litre per hour

Number of hours water will take to fill the reservoir
= $\frac{108000}{3600}$ = 30 hours

Hence,
it will take 30 hours to fill the reservoir.

Answer 2

Answer:

Step-by-step explanation:

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.
