During a lifetime, a heart beats 3.1 x 10^9 times and it beats 91 times in one minute. Thus, we can use cross multiplication to determine the number of minutes in the person's lifetime as follows: number of minutes in person's lifetime = (3.1 x 10^9) / 91 = 34.0659 x 10^6 min
One year has 365.25 days (disregarding leap). Each day has 24 hours and each hour has 60 minutes. Therefore, one year = 365.25 x 24 x 60 = 525960 minutes
We can now use cross multiplication to determine the number of years of a person's lifetime as follows: number of years = (34.0659 x 10^6 x 1) / 525960 = 64.76899 years.
