A typical person has an average heart rate of 75.0 beats/min. Pay close attention to significant figures in this question.
frozen [14]

The number of beats  the person have in 1.7 years is  6.7 x 10⁷ beats.

<h3>Number of beats of the person</h3>

The number of beats of the person is calculated as follows;

n = bt

where;

  • b is the beat rate
  • n is number of beats
  • t is time or duration

b = 75 beats/min

t = 1.7 years = 893520 mins

n = 75 beats/min x 893520 mins

n = 67,014,000

n = 6.7 x 10⁷ beats

Thus, the number of beats  the person have in 1.7 years is  6.7 x 10⁷ beats.
