If sherry took her pulse for 6 second and felt 14 beats, what would her heart rate be?

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 =

x =

x = 140 beats/min

x = her heart rate = 140 beats/min

answer; the above statement is (true);
