An eon of time is defined as 1 billion years (1x10 9yrs) in scientific notation. How long is this in minutes? (Assume 1 year =365.25days.

• Math -

1 yr=365.25 days.
1x10^9yrs = 365.25 x10^9 days.
1 day = 24 hrs.
365.25 x10^9 days = 24 x 365.25 x 10^9 = 8766 x 10^9 hours.
1 hr = 60 min.
8766 x 10^9 hrs = 60 x 8766x10^9 hrs=
525960 x 10^9 min =5.25960 x 10^14 min
