Question

A heart beats 740 times during 5 minutes of running. While resting you record the heart beating 12 times in 10 seconds. What is the difference between the heart rate when you are running versus resting.

Answer 1

Answer:

76 beats per minute

Step-by-step explanation:

What's the difference in the heart rate when you are running versus resting?

The heart rate is measured in beats per minute.

Let's find out what's the heart rate while running.  It beat 740 times in 5 minutes... how many times in a minute (in average)?

So, 740 / 5 = 148 beats per minute (bpm) while running.

At rest, you measured 12 beats in 10 seconds... there are 60 seconds in a minute, so we need to multiply that 12 beats by 6 to obtain the result for a minute.

So, 12 * 6 = 72 beats per minute while resting.

The difference is 148 - 72 = 76 beats per minute.
