How many years older will you be 1.30 billion seconds from now? (Assume a 365-day year.)

41.2 years older

Explanation:

Note: 60 seconds makes 1 minute

Also note that 1.3 billion seconds = 1300000000 seconds

60 s = 1 min,

Then, 1300000000 s = (1300000000/60) min.

= 21666666.667 min.

Also

Note: 60 minutes makes one hour

60 min = 1 hour

21666666.667 min = (21666666.67/60) hours

= 361111.111 hours.

Also,

Note: 24 hours makes 1 day.

24 hours = 1 day,

361111.11 hours = (361111.11/24) days

= 15046.296 days.

Also

Note: 365 days makes one year

365 days = 1 year

15046.296 days = (15046.296/365) years

=41.2 years.

Hence i will be 41.2 years old from now.
