Question #020e3

Answer 1

31.7 years

Explanation:

1) 1 year=365 days = 8760 hours = 525600 minutes = 31536000 seconds

2) 1 year - 31536000 seconds
x years - 1 000 000 000 seconds

x=`\frac{1*1 000 000 000}{31536000}=31.70979 ~ 31.7` years

*** not sure, maybe I needed to use that 1 year = 365.25 days ***
