Question

The typical consumption of water for drinking is 2 liters per day. However, someone exercising vigorously perspires at a rate of about 1 liter per hour. Compare the water use for drinking, cooking, toilet flushing (4 flushes/day), and showering for a "couch potato" who drinks 2 liters/day and an "exercise freak" who also must replace fluids for 6 hours/day of vigorous exercise. The couch potato showers once per day for 3 minutes, while the exercise freak showers 3 times per day for 10 minutes per shower. Express your results in L/day, and then convert them to gallons/day.

Explanation / Answer

Well, here there something important: the human body doesn't holds water consumed, based in this we can take several assumptions.

1) the quantity of toilet flushes are equivalent to the volumen of water consumed. if a couch potato have 4 flushes/day, it means is one flush per half liter

2) the drinking difference is 6 L assuming the excercise freak drink as much water as he sweat

3) if excercise freak consume 6L more than couch potato, excercise freak have, then, 12 flushes more per day

4) if the shawer flow is equal for both, excercise freak consume 10 more times than couch potato per day in showers...

assuming a shower flow of 10 L/min, are 300 L/day + 6L/day + 12 flushes more.
