Question

The average human heart beats 1.15*10⁵ times per day. There are 3.65*10² days in one year. How many times does the average human heart beat in one year?

a) 41,975,000
b) 41,900,000
c) 41,725,000
d) 42,025,000

Answer 1

The average human heart beats 41,975,000 times in one year.

Step-by-step explanation:

The average human heart beats 1.15*10⁵ times per day. To find out how many times the heart beats in one year, we need to multiply the number of beats per day by the number of days in a year.

Number of beats per day = 1.15*10^5

Number of days in a year = 3.65*10²

Number of beats per year = (1.15*10^5) * (3.65*10²) = 41,975,000

Therefore, the average human heart beats 41,975,000 times in one year.
