Question

There are 12-thirty second ads and 24-fifteen second ads. how many ads are there in minutes

Answer 1

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

Answer 2

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

`t = 12(30) + 24(15)\\t = 720`

Now let's convert this to minutes.

`m = 720/60\\m = 12`

There are a total of 12 minutes worth of ads.
