1
Find how many complete hours fit into 690 minutes.
Divide 690 minutes by 3,600:
690 ÷ 3,600 = 11.5
This means 690 minutes contains11 full hours, plus a little extra time.

Find how many seconds are left.
We know that 11 hours contain:
11 × 3,600= 39,600 seconds
We started with 41,400 seconds. Subtract the seconds we've already used:
41,400 − 39,600= 1,800 seconds
That leaves 1,800 seconds after counting the 11 full hours.
Final answer
690 minutes = 11 hours and 1,800 seconds
11 full hours + 1,800 seconds left over.
