Answer:
4.41 × 10¹⁷ Seconds
Explanation:
For this problem we will first find out the number of days in 14 billion years.
Remember that 1 billion is equal to 1,000,000,000 or 10⁹. So, 14 billion years will be written as 14,000,000,000 or 1.4 × 10¹⁰ years.
Therefore, In
1 year there are = 365 years
So, In
1.4 × 10¹⁰ years there will be = X years,
Solving for X,
X = 1.4 × 10¹⁰ years × 365 days / 1 year
X = 5.11 × 10¹² days
Secondly, as there are 24 hours per day and each hour has 60 minutes and each minute has 60 seconds, therefore, the number of seconds per day are calculated as,
Number of Sec/day = 24 × 60 × 60
Number of Sec/day = 86400 sec/day
Hence, If,
1 day has = 86400 seconds
then,
5.11 × 10¹² days will contain = X seconds
Solving for X,
X = 5.11 × 10¹² days × 86400 sec / 1 day
X = 4.41 × 10¹⁷ Seconds
