Find how many seconds are left.
We know that 5 weeks contain:
5 × 604,800= 3,024,000 seconds
We started with 3,564,000 seconds. Subtract the seconds we've already used:
3,564,000 − 3,024,000= 540,000 seconds
That leaves 540,000 seconds after counting the 5 full weeks.
Final answer
990 hours = 5 weeks and 540,000 seconds
5 full weeks + 540,000 seconds left over.
