Question

For every 15 minutes of a show, there are two minutes to commercial. At this rate, if leila has seen 45 minutes of a show, how many minutes has she been watching tv together

Answer 1

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.
