Your lungs take in about .047 L of air with each breath. How much air might you breathe if you live to be ...

Question

100 years old? Write the amount in standard from and in scientific notation.

Answer 1

Breathing rate is once every 4 or 5 seconds, and there are just over 30 million seconds in a year. So say about 7 million breaths a year, and take it from there yourself.

Answer 2

The question is not complete. In order to retrieve the result, more data (such as how many times a minute does a human breathe) is required.

THe formula for a 100 year old person having breathed n times would be:
n = 0.047 * x * 60 * 24 * 365 * 100 + 0.047 * x * 60 * 24 * 25
where x = number of times a human breathes a minute

The second part (after the + sign) includes the leap year days. There are 25 leap year days as there is one leap year once a 4 years.

The question contains an incorrect assumption, as the amount a person inhales in his or her lungs may vary by age.

Answer 3

I think we take in more than 0.047 liters of air in each breath. We breathe about 8 times per minute, I think.
