2
Find how many seconds are left.
We know that 23 weeks contain:
23 × 604,800= 13,910,400 seconds
We started with 14,040,000 seconds. Subtract the seconds we've already used:
14,040,000 − 13,910,400= 129,600 seconds
That leaves 129,600 seconds after counting the 23 full weeks.
Final answer
3,900 hours = 23 weeks and 129,600 seconds
23 full weeks + 129,600 seconds left over.
