Question

If your heart rate is 151 beats per minute during strenuous exercise, what is the time per beat in units of seconds? s/beat =Round your answer to two decimal places

Answer 1

0.40 s/beat

Step-by-step explanation

Given:

• A heart rate of 151 beats per minute

Find:

• The time per beat (in seconds/beat)

So, we know that the heart rate is given in beats/minute, but we want to find the time per beat in seconds/beat. To do so, first, we have to find the heart rate in beats/second. If 60 seconds is 1 minute,

`151(beat)/(min)\cdot(1min)/(60s)=(151)/(60)(beat)/(s)`

Now, the reciprocal will be the time per beat,

`(60)/(151)(s)/(beat)\approx0.40s`

Hence, the time per beat is 0.40 s/beat, rounded to two decimal places.
