A typical person has an average heart rate of 75.0 beats/min. Calculate the following a)How many beats does she have in 7.0 year
hram777 [196]

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>
