Express your answers to problems in this section to the correct number of significant figures and proper units. A person measures his or her heart rate by counting the number of beats in 30 s. If $40 \pm 1$ beats are counted in $30.0 \pm 0.5 \mathrm{s},$ what is the heart rate and its uncertainty in beats per minute?
