Nice first teaser
1815 WHAT??? Didn't your math teacher ever teach you to identify your UNITS? And since you phrased your question in minutes and seconds, shouldn't the answer be it the same form?
30 minutes and 15 seconds -now THAT"S a proper answer. Sorry-but at best you get only half credit for this problem

Hey Uncle Mikey, the question reads, "How many seconds...". Good teaser.
2:48 = 168 seconds
2:48 + 15 = 183 seconds
9 @ 183 + 1 @ 168 =
9*183 + 168 =
1647 + 168 =
1815
Easy but fun
