Heart beats 2400 times during 20 minutes of running. while resting you record your heart beating 17 times in 15 seconds. what is the difference between your heart rate when she is running versus resting

1,360 beats when she is resting

Step-by-step explanation:

17 times per 15 seconds in a 20 minute span

how many 15 seconds are in 60 seconds.

There is 4 periods of 15 minutes in one minute

17 * 4 = 68

68 * 20 = 1360

I think that is correct

Hello, while you are running heart beating 2400 times in 20 minutes, so we can say that is equal to:

2400 times / 20 minutes * 1 min / 60 seconds, thus,

(2400 times * 1 min) / (20 min * 60 seconds)

2400 times / 1200 seconds = 2 times / second, the heart beats 2 times per second when you are running. For the case when we are resting, then:

17 times / 15 seconds --> 17/15 aprox. 1.1333... , so the heart beats 1.13 times aprox. when we are resting.

Thus, (rate of beating running) - (rate of beating resting) = 2 - 1.13 = 0.87

So, we can say that the heart beats 0.83 times more (aprox.) when we are running than when we are resting. I hope I help you. Sorry for my English.
