Answer:

54 beats/minute

Explanation:

First find the average heart rate from the data given

16+20+18=54

54/3=18

So her average heart rate for 20 seconds is 18

To find her heart rate in beats per minute multiply 18 times 3 because 20 seconds is a third of a minute

18x3=54

So, her average resting heart rate in beats/minute is 54
