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.
