Question

How do you get the answer to 18,000 seconds = hrs?

Answer 1

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.

Answer 2

You would divide 18,000 seconds by 60 seconds (which is equivalent to a minute)
the you would take the number you just got and divide that number by 60 minutes (which is equivalent to an hour)
that should give you the correct answer
