Question
Shannon takes her pulse for 20 seconds each and records 40 beats within this time. Work out her heart rate per minute using this data
Solution
Sure, here are the steps to calculate Shannon's heart rate per minute:
-
First, we know that Shannon's pulse is 40 beats in 20 seconds.
-
We need to find out how many beats her heart would beat in a minute. Since there are 60 seconds in a minute, we need to scale up the number of beats accordingly.
-
To do this, we divide 60 (seconds in a minute) by 20 (the number of seconds she counted her pulse). This gives us a factor of 3.
-
We then multiply the number of beats she counted (40) by this factor (3).
-
40 beats * 3 = 120 beats.
So, Shannon's heart rate is 120 beats per minute.
