Question

Маша пришла в школу в 8ч 15мин.мв этот день у нее было 4 урока по 40 мин,а после уроков она задержалась на 10 мин. каждая перемена длилась 15 мин. в какое время Маша вышла из школы?

Answer 1

4 урока * 40 минут каждый = 160 минут, то есть 2часа 40 минут.
3 перемены * 15 минут каждая = 45 минут.
складываем. 8.15 + 2.40 + 0.45 + 0.1 = 8.15 + 2.40 + 0.55 = 8.15 + 3.35 =
 =  В 11 часов 50 минут Маша ушла из школы.

Answer 2

Calculation of Time Spent in School

To determine the time at which Masha left school, we need to calculate the total time she spent in school and add it to her arrival time.

Masha arrived at school at 8:15 AM. She had 4 lessons, each lasting 40 minutes. After her lessons, she stayed for an additional 10 minutes. Each break between lessons lasted 15 minutes.

Let's calculate the total time Masha spent in school:

- Time spent in lessons: 4 lessons x 40 minutes/lesson = 160 minutes - Time spent on breaks: 3 breaks x 15 minutes/break = 45 minutes - Additional time after lessons: 10 minutes

Now, let's add up the total time:

- Total time spent in school: 160 minutes (lessons) + 45 minutes (breaks) + 10 minutes (additional time) = 215 minutes

Calculation of Departure Time

To calculate the time at which Masha left school, we need to add the total time spent in school to her arrival time:

- Arrival time: 8:15 AM - Total time spent in school: 215 minutes

To calculate the departure time, we add the total time spent in school to the arrival time:

- Departure time: 8:15 AM + 215 minutes = 11:50 AM

Therefore, Masha left school at 11:50 AM.

Please note that the above calculation assumes that the lessons and breaks occurred consecutively without any additional delays or interruptions.
