The current heart rate of John at the given number of pulses and time is 1.2 pulse per second.
The given parameters;
- Time of count by John, t = 10 s
- Number of pulses counted, n = 12 beats
The heart rate is defined as the number of pulses or beats per second.
The heart rate of John is determined by dividing the total pulses by the time of count.
The current heart rate of john is calculated as follows;
[tex]R = \frac{12 \ pulses}{10 \ s} \\\\R = 1.2 \ pulse \ per \ second.[/tex]
Thus, the current heart rate of John at the given number of pulses and time is 1.2 pulse per second.
