Answer:  4000 beats per hour

Step-by-step explanation:

<u>200 beats </u>     X   <u> 60 minutes</u>    

3 minutes               1 hour

The term 'minutes' cancel out therefore you are left with beats per hour

<u>200 x 60</u>       =    <u>12000</u>    =  4000 beats per hour

      3                         3

200 times / 3 minutes = x times / 60 minutes

3x = 12000

x = 4000 times in an hour

A person's heart will beat 4000 times in an hour.

Hope this helps!! :)
