water is pouring into a cuboidal reservoir at the rate of 50 litres per minute if the volume of the reservoir is 150m3,find the number of hours it will take to fill the reservoir.
final answer is 50 hours explain
Answers
Given, volume of reservoir = 108 m3
Rate of pouring water into cuboidal reservoir = 60 liters/minute
= 60/1000 m3 per minute
Since 1 liter = (1/1000 )m3
= (60 x 60) / 1000 m3 per hour
Therefore, (60* 60) /1000 m3 water filled in reservoir will take = 1 hour
Therefore 1 m3 water filled in reservoir will take = 1000/ (60 x 60 ) hours
Therefore, 108 m3 water filled in reservoir will take = (108 x1000) / ( 60 x 60 ) hours = 30 hours
Answer: It will take 30 hours to fill the reservoir.
Step-by-step explanation:
We need to fill 150 m³ of volume.
The water is filled 50 L per minute.
Conversion: 1 L=0.001 m³
50 L will be 50×0.001 m³ = 0.05 m³
Unitary method:
If 0.05 m³ is filled in 1 minute,
then 150 m³ will be filled in 150/0.05 = 3000 minutes.
3000/60 = 50 hours
