1
Find how many complete weeks fit into 520 hours.
Divide 520 hours by 604,800:
520 ÷ 604,800 = 3.095238095238
This means 520 hours contains3 full weeks, plus a little extra time.
2
Find how many seconds are left.
We know that 3 weeks contain:
3 × 604,800= 1,814,400 seconds
We started with 1,872,000 seconds. Subtract the seconds we've already used:
1,872,000 − 1,814,400= 57,600 seconds
That leaves 57,600 seconds after counting the 3 full weeks.
Final answer
520 hours = 3 weeks and 57,600 seconds
3 full weeks + 57,600 seconds left over.
