Answer:  The person lived for 80.66 years.

Explanation:

Heart beat of the person = 73 beat /min

Number of total heart beats = 3.1\times 10^{9}

Life span of the person : \frac{\text{Total heart beats of the person}}{\text{Heart beat per minute}}=\frac{3.1\times 10^{9} beats}{73 beat/min}

1 year =525600 mins

Life span = 0.0424\times 10^{9} min=80.66 years

The person lived for 80.66 years.

I hope this helped, have a nice day!
