How many minutes in 12 years?

Answer 1

* Fast Approximation:

1 day = 24 (hour) x 60 (min/hour) = 1440 minute

1 year = 365 (day) x 1440 (min/day) = 525600 minute

12 year = 12 (year) x 525600 (min/year) = 6 307 200 minute

* Considering 3 leap years in between:

3 x 24 (hour) x 60 (min/hour) = 4320 minute

12 year (+ leap years) = 6 311 520 minute

* Considering the mean tropical year (365 days + 5hs + 48m + 45s)

12 (tropical years) = 6 311 385 minute
