Answer 3

Calculating the Duration of the Dictation

To calculate the duration of the dictation, we can use the following formula:

Duration of Dictation = Total Lesson Time - Time Spent on Other Activities

Given: - Duration of each lesson = 45 minutes - Total number of lessons = 5 - Activity during 3 out of 5 lessons: Dictation

Using the given information, we can calculate the duration of the dictation.

Calculation

- Total lesson time = 45 minutes/lesson * 5 lessons = 225 minutes - Time spent on dictation = 45 minutes/lesson * 3 lessons = 135 minutes - Duration of dictation = Total lesson time - Time spent on dictation = 225 minutes - 135 minutes = 90 minutes

Therefore, the duration of the dictation was 90 minutes.
