A person measures his or her heart rate by counting the number of beats in 30 s. If 47 ± 1 beats are counted in 30.0 ± 0.5 s, what is the uncertainty in the heart rate in beats per minute?

Step 1
First, we need to find the heart rate in beats per minute. Since the person counted 47 beats in 30 seconds, we can multiply this by 2 to find the beats per minute: Heart rate = 47 beats * 2 = 94 beats per minute Show more…
