Question 213851
I hope you have a calculator for this one!!  A billion seconds is 1,000,000,000 seconds.  First change this to minutes and then to hours by dividing by 60 and by 60 again.  This would be 


{{{1000000000/3600=277777.778 }}} hours


Next change this to day by dividing by 24 hours per day, which is 11574.074 days.


Finally, divide by 365.25 days, which gives you 31.688 years.


If you are younger than 31, you haven't lived 1 billion seconds yet, but watch out!!  That billionth second will fly by you before you know it!
