Question

Assume that a human heart is capable of beating about 2.8 billion times in a lifetime. If a
person’s average heart rate is 72 beats per minute, what is that person’s life span? Express your
answer in years and days. (For example, 5 years 142 days.) Don’t forget to take leap years into
account!

Answer 1

2.8 x 10⁹ / 7.2 x 10 = 0.388888 x 10⁸ minutes

3.88888 x 10⁷ / 1.440 x 10³ = 2.7 x 10⁴ days

 

You can convert days to years.
