How many times does a rabbits heart beat in one hour

mash [69]

<span>A rabbit’s heart rate should be 120-150 beats per minute so you just multiply 120 by 60 and 150 by 60 and the numbers in between that should be the amount of times a rabbit hearts beats in one hour. 60 x 120 = 7,200 and 60 x 150 = 9,000. A rabbit's heart beats between 7,200 and 9,000 times an hour. </span>
