Answer 2

Normal heart beat per minute = 80 beats

heart beat in an hour = 60× 80 = 4800

Heart beat in one day = 24 x 60 x 80 = 24 x 4800 = 115200

One year = 365 days = 365 x 24 hours = 365 x 24 x 60 minutes

∴ Heart beats in a year = 365 x 24 x 60 x 80 = 42048000 times

heart beats in 80 years =42048000× 80 =3,363,840,000 times!

In 80 years our heart would have beaten approximately 3,363,840,000 times! That's over 3 billion heartbeats!
