To convert minutes into hours, remember one simple rule:
1 hour = 3,600 seconds
Every 3,600 seconds make 1 full hour.
1
Find how many complete hours fit into 345 minutes.
Divide 345 minutes by 3,600:
345 ÷ 3,600 = 5.75
This means 345 minutes contains5 full hours, plus a little extra time.
2
Find how many seconds are left.
We know that 5 hours contain:
5 × 3,600= 18,000 seconds
We started with 20,700 seconds. Subtract the seconds we've already used:
20,700 − 18,000= 2,700 seconds
That leaves 2,700 seconds after counting the 5 full hours.
Final answer
345 minutes = 5 hours and 2,700 seconds
5 full hours + 2,700 seconds left over.
