"If the 'Boil' pushes out 104 million gallons of water per day, then how
many gallons are pushed out:
a) in two hours?
b) in two minutes?
c) in 30 seconds?
d) in 10 days?
e) How many gallons do you use on average at your house for things like
taking a bath, taking a shower, doing a load of laundry, running your
dishwasher, or washing a car?"
The total number of gallons pushed out a day is 104 million. So we divided
that number by 12 because 24 hours divided by 2 hours would be 12 hours. So,
our answer for a is 8,666,666.66 gallons.
In two minutes the 'boil' would push out 72,222.22 gallons of water.
In 30 seconds, it would push out 18,055.55 gallons We found this answer out
by dividing it by 4, because 30 seconds goes into two minutes four times.
In 10 days, it would do 1,040,000,000 gallons of water.
According to the American Water Works Association -
http://www.awwa.org/Advocacy/pressroom/statswp5.cfm
a typical family uses an average of 74 gallons of water indoors and almost
that much again if they water the lawn outdoors and wash the car. We don't
do of that in the wintertime in Vermont.
