Find how many seconds are left.
We know that 4 hours contain:
4 × 3,600= 14,400 seconds
We started with 16,680 seconds. Subtract the seconds we've already used:
16,680 − 14,400= 2,280 seconds
That leaves 2,280 seconds after counting the 4 full hours.
Final answer
278 minutes = 4 hours and 2,280 seconds
4 full hours + 2,280 seconds left over.
