Question

A person normally breathes about 6 liters of air per minute. The life expectancy of a person in the United States at birth is about 80 years. Use scientific notation to estimate the total amount of air a person born in the United States breaths over a lifetime

Answer 1

525600 minutes = 1 year

A person normally breathes about 6 liters of air per 1 minute

They are asking for how many liters does a person breathe in the U.S. for a life expectancy of 80 years



The equation above depicts that. The minutes cancel, and so do the years. What you have left is just liters. Therefore, your answer will be in liters

The answer is 252288000 liters of air

The answer in scientific notation is


`2.52288 * {10}^(8) \: liters`
