The real amount is found like this: there are sixty seconds in a minute and 60 minutes in an hour, so first you multiply sixty by sixty (60*60 or 602) to equal 3600. You then multiply 3600 by five to get the amount for five hours (3600*5) to equal 18000. For minutes, there are sixty seconds in a minute, and five minutes, so you multiply sixty by five (60*5) to equal three hundred. You then have fifteen seconds, and there are fifteen seconds in fifteen seconds, so you add them all together (18000+300+15) to equal 18315 as your total amount of seconds.
