Question

anonymous · Answer

The time difference between 6:00 and 6:30 is 30 min
The heart beat difference is 81-63=18 beats
so during 30 min the heart changed beat by 18 beats
in other words 18 beats /30 min
18/30 beats/min = 0.6 beats/min
the rate of change in heart rate is 0.6 beats/min 

((((is this correct))
