Question

A human heart beats an average of 80 beats per minute.
How many heart beats is this in 80 years?​

Answer 1

Answer:

first of all

human heart beats 80 per min

then 80 years =?

then we know

80 years (20 leap years)

so, 80×365= 29,200 days (without leap years)

so, 29,200+20=29,220 days (with leap years)

so, 29,220 × 24= 7,01,280 hours

so, 7,01,280 × 60= 4,20,76,800 minutes

so now we can say

1 minute= 80 heart beats

4,20,76,800 minutes= x

therefore

x=4,20,76,800 × 80

x=3,36,61,44,000 heart beats

is the answer.......
