1470.51 – Heartbeats per Month


How many times will your heart beat this month?


Solution

Count the number of your heartbeats in one minute. Let xx represent the number of heartbeats you counted. Then:

xbeats1min60min1hr24hrs1day31days1month=44640xbeats1month\frac{x beats}{1 min}\cdot\frac{60 min}{1 hr}\cdot\frac{24 hrs}{1 day}\cdot\frac{31 days}{1 month}=\frac{44640x beats}{1 month}

This means you can multiply the number of heartbeats you counted by 44,640 to get the number of heartbeats in one month. They say that your heart works as hard in one beat as you do when you squeeze a tennis ball. Awesome, no?
