Answer:

51 minutes.

Explanation:

We have been given that for every 15 minutes of a show, there are two minutes to commercial. At this rate, Leila has seen 45 minutes of a show. We are asked to find the time for which Leila has been watching TV.

We will use proportions to solve our given problem.


\frac{\text{Minutes of TV show + Advertisement}}{\text{Minutes of TV show}}=(15+2)/(15)


\frac{\text{Minutes of TV show + Advertisement}}{\text{Minutes of TV show}}=(17)/(15)

Upon substituting our given values, we will get:


\frac{\text{Minutes of TV show + Advertisement}}{45}=(17)/(15)


\frac{\text{Minutes of TV show + Advertisement}}{45}* 45=(17)/(15)* 45


\text{Minutes of TV show + Advertisement}=(17)/(1)* 3


\text{Minutes of TV show + Advertisement}=51

Therefore, Leila has been watching TV together for 51 minutes.
