Let's find the total number of seconds these adds take up:

[tex]t = 12(30) + 24(15)\\t = 720[/tex]


Now let's convert this to minutes.

[tex]m = 720/60\\m = 12[/tex]


There are a total of 12 minutes worth of ads.

First you multiply 30 by 12 = 360
Then you multiply 24 by 15 = 360
Then multiply 360 by 2 or add 360 plus 360 = 1,020
Then you divide 1,020 by 60 = 17
60 = 1 min
So the answer is 17 min
