ANSWER:
A faucet drips at a rate of 1 drop per every second.Number of liters wasted are 1576.6 liters.
SOLUTION:
Given, a faucet drips at a rate of 1 drop per every second.
We need to find how many liters of water are wasted per year.
Now, let us find how many seconds are there for an year.
1 year = 365 days[ consider non – leap year]
= 365 [tex]\times[/tex] 24 hours
= 365 [tex]\times[/tex] 24 [tex]\times[/tex] 60 minutes
= 365 [tex]\times[/tex] 24 [tex]\times[/tex] 60 [tex]\times[/tex] 60 seconds
= 31,536,000 seconds
Therefore number of drops wasted per year = 1 [tex]\times[/tex] 31,536,000 seconds
No. of drops = 31,536,000. But we are asked how many liters.
No. of liters = [tex]\frac{\text {number of drops}}{20,000}[/tex] [when 1 liter = 20,000drops]
[tex]\text { No. of liters }=\frac{31,536,000}{20,000}[/tex]
No. of liters = 1576.6 liters
Hence, number of liters wasted are 1576.6 liters.
