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
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
