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 390 minutes.
Divide 390 minutes by 3,600:
390 ÷ 3,600 = 6.5
This means 390 minutes contains6 full hours, plus a little extra time.
2
Find how many seconds are left.
We know that 6 hours contain:
6 × 3,600= 21,600 seconds
We started with 23,400 seconds. Subtract the seconds we've already used:
23,400 − 21,600= 1,800 seconds
That leaves 1,800 seconds after counting the 6 full hours.
Final answer
390 minutes = 6 hours and 1,800 seconds
6 full hours + 1,800 seconds left over.
