Question

open ended question
in this video we are told to find our heart rate for 10 seconds, and then we multiply the number of heart beats by 6. critical think: why do we multiply by 6?
ready? enter your answer here.

Explanation:

To find the heart rate per minute (60 seconds), we first count beats in 10 seconds. Since 60 seconds is 6 times 10 seconds (because \( \frac{60}{10} = 6 \)), multiplying the 10 - second beat count by 6 gives the beats per minute (the standard heart rate measurement unit).

Answer:

We multiply by 6 because there are 60 seconds in a minute, and 60 divided by 10 (the time we counted heartbeats for) equals 6. So multiplying the number of heartbeats in 10 seconds by 6 gives the heart rate in beats per minute.
