If a person was in the phone for
512 seconds

How can this be worked out mathematically as to how many hours the person was on the phone for?

Easiest way please?

Thanks

If you divide seconds by 3600 you get hours, as there are 3600 seconds in an hour.

60 seconds in a minute, 60 minutes in an hour!

512s/3600s = 0.14hrs

so 0.14hrs, is less then an hour, so guess it would be 14mins then? right or wrong.

Wrong....8.5 minutes.

8.5 minutes is 0.14 of an hour.

8.5 minutes talk time = 512 seconds

0.1422 hours doesn't mean 14 mins

0.14 * 60 correct?

Details:

512 seconds = 8.5333 Minutes (take 512 and divide that by 60, since there are 60 seconds in 1 minute)
512 seconds = 0.1422 hours (take 512 and divide that by 3600 since there are 3600 seconds in 1 hour: 60x60=3600)

512 divide by 60 (seconds) = 8.5 minutes
