When a person reaches the age of 35 for how many seconds has that person lived?

1.104e+9, that is the answer good sir

60 sec = 1 minute

60 min = 1 hour

24 hr = 1 day

365 days = 1 year

So, a 35-year old person is roughly 365 (35) days old, or 12775 days.

Continuing applying conversion factors until you've calculated how many seconds that is. The next calculation is 12775 days times (24 hours) / (1 day)
