1
Find how many complete hours fit into 45,000 seconds.
Divide 45,000 seconds by 3,600:
45,000 ÷ 3,600 = 12.5
This means 45,000 seconds contains12 full hours, plus a little extra time.

Find how many seconds are left.
We know that 12 hours contain:
12 × 3,600= 43,200 seconds
We started with 45,000 seconds. Subtract the seconds we've already used:
45,000 − 43,200= 1,800 seconds
That leaves 1,800 seconds after counting the 12 full hours.
Final answer
45,000 seconds = 12 hours and 1,800 seconds
12 full hours + 1,800 seconds left over.
