Answer 1

Given:

A person is 100 million seconds old.

To find:

How old is a person who is 100 million seconds old?

Solution:

From given, we have,

A person is 100 million seconds old.

we know that,

1 year = 365 days 24 hours 60 minutes 60 seconds

1 year = 31536000 seconds

1 second = 1/31536000 year

100 million = 100,000,000

100,000,000 × 1 second = 1/31536000 year × 100,000,000

100 million seconds = 3.17 years

Therefore, a person is 3.17 years old.
