If there are 24 hours in a day and 60 minutes in a hour. We'll multiply them together to find how many minutes are in a day.
24×60=1,440
In a day there 1,440 minutes, if your heart beats 65 times per minute, we can use the equation
Beats=65(minutes)
We can then plug in the numbers to solve for beats
Beats=65×1,440
Beats=93,600
In a day, your heart beats 93,600 times
