There are .66 minutes in 40 seconds

There are two, 30 second periods in one minute.

There are 172,800 seconds in 48 hours (48hours x 3600seconds/1hour= 172800)

Just under 3168809 years

1 minute = 60 seconds 15 minutes = 15 x 60 = 900 seconds

The answer to this question is very easy to calculate. Using a pocket calculator, any high school student should be able to answer this question correctly in a few seconds:

Multiply 60 (the number of seconds in a minute) x 60 (the number of minutes in an hour) x 24 (the number of hours in a day) x 365* (the number of days in a year), then multiply by 2 (the number of years at issue in the question).

* Adjust accordingly for a leap year.
