To calculate the time it would take for a cow's heart to beat 10,000 times, we can use the cow's heart rate of 50 beats per minute.
If the cow's heart beats 50 times in 1 minute, we can divide 10,000 by 50 to find out how many minutes it would take.
So, 10,000 divided by 50 equals 200.
Therefore, it would take approximately 200 minutes for the cow's heart to beat 10,000 times.
