Estimation:
23 --> rounded to 20
71 --> rounded to 70
70 + 20 = 90. I rounded both numbers down so the exact sum must be only a little greater than my estimate.
First you'd convert the seconds into minutes by dividing.
18,000 / 60 (60 secs in a min) = 300 minutes
Then, similarly, you would convert the minutes into hours.
300 / 60 (60 mins in an hr) = 5 hours
The answer is 5 hours.
