15 years of marriage. :)
15 years
If you assume that each generation had a child at the age of 18 and the eldest was 90 years old, then there would be 6 generations at the reunion. This can be greater if the eldest is older than 90 and each generation had a child earlier than 18. For example there would be 7 generations at the reunion if the eldest was still 90 and each generation had a child at 15 years of age.
30 years. 15 - -15 = 15 + 15 = 30.
10 years??30 years I believe, from -15 to +15 is 30
15 years = 131,487.192 hours.
