on the average your heart beats about 72 time per minute. at this rate, about how many time will it beat in 30-day month and in a year and in your lifetime, if you live to 72 years of age?

72 times a minutes * 60 min./hr * 24 hr/day * 365.25 days a year * 72 years

=3*109 times approximately.

Tanyas heart beats 68 times per minute how many times does it beat in one hour

To answer this question, we need to determine the number of beats per minute, then calculate the beats per month, year, and lifetime.

First, the average heart rate is given as 72 beats per minute.

To find the number of beats in a 30-day month, we multiply the average beats per minute by the number of minutes in a day (24 hours x 60 minutes):

72 beats/minute x 24 hours/day x 30 days = 103,680 beats/month

Next, to find the number of beats in a year, we multiply the beats per month by the number of months in a year (12 months):

103,680 beats/month x 12 months/year = 1,244,160 beats/year

Finally, to find the number of beats in a lifetime, we multiply the beats per year by the number of years (72 years):

1,244,160 beats/year x 72 years = 89,462,720 beats in a lifetime

Therefore, if you live to 72 years of age, your heart would beat approximately 1,244,160 times per year and approximately 89,462,720 times in your lifetime.
