Question

a humman beats about times in a day​

Answer 1

• The heart weighs between 280 and 340 grams in men and about 230 to 280 grams in women. The heart beats about 3 billion times in a lifetime - about 100,000 times in a day. An adult heart beats 60 to 80 times every minute. A new-born's heart beats faster than adult hearts - about 70 to 190 beats per minute.

Answer 2

Explanation:

As we know that our heart beats almost 72 to 80 times per minute. Let us think that it beats about 75 times per minute approximately.

Now,

Minutes in 1 hour =60 minutes

Minutes in 1 day (24 hours) = 60×24

: = 1440 minutes

Heart beating in 1 day = 1440 ×75(taken approximate heart beat) = 108000 times
