Question

Estimate the number of breaths taken by a human being during an average lifetime. (we estimate an average respiration rate of about 10 breaths per minute and a typical life span of 70 years.) 106 breaths 108 breaths 1010 breaths 1012 breaths 1014 breaths

Answer 1

In this question, we have to estimate the number of breaths taken by a human being during an average life time .

And average respiratory rate of about 10 breaths per minute . And average age of a human being is 70 years .

In 1 minute, number of breaths are 10 breaths .

So in 1 day,number of breaths are

$= 10*60*24 breaths = 14400 breaths$

And for one year, it is

$=14400*365 =5256000 breaths$

And in 7 years, it is

$= 5256000*7 =36792000 breaths$
