Answer:
3.679 ×
Explanation:
Let's assume that average lifespan for normal human being is 70 years.
In 70 years there are 365 days in each year.
70 years = 70 × 365 days
In one day there are 24 hours.
70 years = 70 × 365 × 24 hours
In one hour there are 60 minutes.
70 years = 70 × 365 × 24 × 60 minutes
we estimate an average respiration rate of about 10 breaths per minute. ... (Given)
Thus, for 70 years number of breath are,
n = 70 × 365 × 24 × 60 × 10
n = 3.679 ×
Hence, estimate number of breath over a period of life is 3.679 × .
