Question

Kim has a leaky faucet in her kitchen and asks Eric to come over and take a look at it. Kim estimates that the faucet in her kitchen drips at a rate of 1 drop every 2 seconds. Eric wants to know how many times the faucet drips in a week. Help Eric by showing your calculations below.
Kim estimates that approximately 575 drops fill a 100 milliliter bottle. Estimate how much water her leaky faucet wastes in a year.

Answer 1

ok, so if we have 1 drop every 2 seconds, that means we have 30 drops every minute (60 seconds/2 drops per second). There are 60 minutes in an hour, so we have 1800 drops per hour (60 minutes*30 drops). There are 24 hours in a day, so we have 43,200 drops per day (24 hours*1,800 drops). Assuming that it is not a leap year, we have 365 days in year, so (365 days*43,200 drops) 15,768,000 drops in a year. Now we divide 15,768,000 by 575 to get 27,422.6087 millimeters of water per year.
