Question

5. В соответствии с законом 21.04.2014 №248-ФЗ "Об исчислении времени" на территории Российской Федерации устанавливаются 11 часовых зон. Самолет вылетел из Оренбурга ( 4-я часовая зона) в Санкт-Петербург (2-я часовая зона) в 9 часов по местному времени Оренбурга. Расчетное время полета составляет 3 часа. Сколько времени будет в Санкт-Петербурге, когда самолет приземлится? Решение запишите

Answer 1

Время в Оренбурге: 9:00, время в этот же момент в Санкт-Петербурге 7:00, так как вычитаем два часа, теперь прибавляем 3 часа к Санкт-Петербургскому времени, получкам: 7 + 3 = 10 часов.
Ответ: Время в Санкт-Петербурге на момент приземления составит 10:00

Answer 2

Calculation of Time Difference

According to the law №248-ФЗ "On Time Calculation" enacted on April 21, 2014, there are 11 time zones established in the territory of the Russian Federation. The flight in question departs from Orenburg, which is in the 4th time zone, and arrives in St. Petersburg, which is in the 2nd time zone. The local time in Orenburg when the plane takes off is 9:00 AM.

Calculation of Flight Duration

The flight duration is given as 3 hours.

Calculation of Arrival Time in St. Petersburg

To calculate the arrival time in St. Petersburg, we need to consider the time difference between Orenburg and St. Petersburg. Since Orenburg is in the 4th time zone and St. Petersburg is in the 2nd time zone, there is a time difference of 2 hours between the two cities.

To find the arrival time in St. Petersburg, we add the flight duration of 3 hours to the local departure time in Orenburg. This gives us a total of 12:00 PM local time in Orenburg when the plane is expected to land.

Next, we need to account for the time difference of 2 hours between Orenburg and St. Petersburg. Since St. Petersburg is 2 hours ahead of Orenburg, we add 2 hours to the local time in Orenburg. This gives us a final arrival time in St. Petersburg of 2:00 PM.

Therefore, when the plane lands in St. Petersburg, it will be 2:00 PM local time in St. Petersburg.

Conclusion

When the plane lands in St. Petersburg, the local time in St. Petersburg will be 2:00 PM.
