Answer 2

Calculating the Total Duration of the Movie

To calculate the total duration of the movie, we can use the following approach:

1. Calculate the Total Duration of Advertisements: - The movie was interrupted by advertisements 9 times, with each block of advertisement lasting 3 minutes. - Therefore, the total duration of advertisements is 9 * 3 = 27 minutes.

2. Calculate the Total Duration of the Movie: - The total duration of the movie, including the interruptions for advertisements, can be calculated by adding the duration of the movie without interruptions to the total duration of advertisements.

3. Determine the Duration of the Movie Without Interruptions: - The movie's uninterrupted duration is 1 hour and 45 minutes, which is equivalent to 60 + 45 = 105 minutes.

Calculation

The total duration of the movie, including the interruptions for advertisements, can be calculated as follows:

Total Duration of Movie = Duration of Movie Without Interruptions + Total Duration of Advertisements Total Duration of Movie = 105 minutes + 27 minutes Total Duration of Movie = 132 minutes

Therefore, the total duration of the movie, including the interruptions for advertisements, is 132 minutes.
