Answer:
29.8 × 10⁸
Step-by-step explanation:
The average life span for human is 79 years
And healthy heart beats 72 times a minute
Now,
Total number of minutes in 79 years = 79 × 365 × 24 × 60
therefore,
The total number of times heart beats in the life span
= 72 × 79 × 365 × 24 × 60
= 2989612800 times
now, to convert it into an answer with 10⁸
divide the result with 10⁸
Hence,
The total number of times heart beats in the life span = 29.8 × 10⁸ times
