Answer:
140
Explanation:
Heart rate is calculated as number of beats made in 1 minute. That is, the unit of heart rate is beats/minute.
Given that Sherry took her pulse and recorded feeling 14 beats in 6 seconds, that her heart made 14 beats in 6 seconds (14 beats/6sec), let's find out how many beats will be made in 1 minute.
14 beats = 6 secs (0.1 min) (recall: 1 min = 60 secs)
x beats = 1 minute
x = [tex] \frac{14 beats*1min}{0.1min} [/tex]
x = [tex] \frac{14*1}{0.1} beats [/tex]
x = 140 beats/min
x = her heart rate = 140 beats/min
