Let us first convert years to minute.
7 years * (365 days / year) * (24 hours / day) * (60
minutes / hour) = 3,679,200 minutes
a. beats = 75.0 beats/min * 3,679,200 minutes
beats = 275,940,000 beats
Since the original given is 7.0 years (2 significant
figures), therefore:
beats = 270,000,000 beats
b beats = 75.0 beats/min * 3,679,200 minutes
beats = 275,940,000 beats
Since the original given is 7.000 years (4 significant
figures), therefore:
<span>beats = 275,900,000 beats</span>
