Answer:
Family will save 3600 gallons of water by replacing the shower-heads.
Step-by-step explanation:
Number of family members in a family = 5
Each member of the family averages shower per day = 8 minutes
Total time for shower = 5×8 = 40 minutes
With a 5 gallon shower-heads each member will use water in a day = 5×40 = 200 gallons
Water consumption in 30 days = 200×30 = 6000 gallons per month
After replacing the shower-heads with 2 gallons per minute shower-heads family will use the amount of water = 40×2= 80 gallons per day
Water used in one month = 80×30 = 2400 gallons
Now water save by the family in 30-day period = 6000 - 2400 = 3600 gallons
Therefore, family will use 3600 gallons less water by replacing the water saving water heads.
3600 gallons of less water will be used by the family with the new showerheads.
Given information:
A family of five members recently replaced its 5-gallon-per-minute showerheads with water-saving 2-gallon-per-minute showerheads.
Each member of the family averages 8 minutes in the shower per day.
The water used by the family with 5 gallons per minute showerheads in one day will be,
[tex]5\times 5\times 8=200\rm \; gallons[/tex]
So, the water used by the family in 30 days with 5 gallons per minute showerheads will be,
[tex]200\times 30=6000\rm \; gallons[/tex]
Now, the water used by the family with 2 gallons per minute showerheads in one day will be,
[tex]5\times 2\times 8=80\rm\; gallons[/tex]
So, the water used by the family in 30 days with 2 gallons per minute showerheads will be,
[tex]80\times 30=2400 \rm\; gallons[/tex]
Now, the amount of water saved by the family in 30 days will be,
[tex]6000-2400=3600\rm\; gallons[/tex]
Therefore, 3600 gallons of less water will be used by the family with the new showerheads.
