Question

Estimate the number of times the earth will rotate on its axis during a human’s lifetime

Answer 1

To estimate Earth's rotations during an average human lifespan of 80 years, one would multiply the average number of days per year, 365.2422, by 80, resulting in approximately 29,219.376 rotations.

Step-by-step explanation:

To estimate the number of times the Earth will rotate on its axis during a human's lifetime, we need an average lifespan and the number of days in a year.

Let's take the average human lifespan to be 80 years. The Earth rotates once every 24 hours or approximately once per day. With a year averaging 365.2422 days, we can calculate the number of rotations in a lifetime by multiplying the number of days per year by the average lifespan.

Solution: 365.2422 rotations/year × 80 years = 29,219.376 rotations

This is a rounded-off estimate; the actual number may be slightly different due to leap years and the exact date of birth and death.

Answer 2

Here we have to calculate the number of rotations made by earth around its own axis in the entire life time of a human being.

The average human life is 50 years .

Each year is 365.5 days

Hence
`50 years =50 *365.5 days`

=18,275 days

The earth rotates around its own axis in 23 hours 56 minutes and 4 second which is approximately equal to 24 hours or one days.

Hence one rotation takes one days.

⇒18,275 days =18,275 rotations

Hence the total number of rotations made by earth around its own axis in the life time of a average human life time will be 18,275 times
