Question

Наш президент собирается совершить деловые визиты в города по следующему маршруту: Москва - Казань - Екатеринбург - Москва. Сколько времени он проведёт в воздухе, если средняя скорость самолета 900 км/ч? Прошу пожалуйста с решением!!

Answer 1

ДУМАЕМ и находим, что
a = 717 км -- расстояние Москва- Казань
b = 717 км - расстояние Казань - Екатеринбург
c = 1416 км -расстояние Екатеринбург - Москва.
РЕШЕНИЕ
Длина маршрута - периметр треугольника.
L = a+b+c = 717+717+1416 = 2850 км - весь маршрут
Время полета по формуле
T = S:V = 2850 : 900 = 3.17 ч = 3ч 10 мин - время полёта - ОТВЕТ
- ОТВЕТ

Answer 2

Calculation of Flight Time

To calculate the total flight time for the president's business visits, we need to consider the distances between the cities and the average speed of the airplane.

The route for the president's visits is as follows: Moscow - Kazan - Yekaterinburg - Moscow.

Let's calculate the flight time for each leg of the journey:

1. Moscow to Kazan: - Distance: - Average speed of the airplane: 900 km/h - Flight time = Distance / Speed = 800 km / 900 km/h = 0.89 hours

2. Kazan to Yekaterinburg: - Distance: - Average speed of the airplane: 900 km/h - Flight time = Distance / Speed = 700 km / 900 km/h = 0.78 hours

3. Yekaterinburg to Moscow: - Distance: - Average speed of the airplane: 900 km/h - Flight time = Distance / Speed = 1400 km / 900 km/h = 1.56 hours

Now, let's calculate the total flight time for the entire journey:

Total flight time = Flight time (Moscow to Kazan) + Flight time (Kazan to Yekaterinburg) + Flight time (Yekaterinburg to Moscow)

Total flight time = 0.89 hours + 0.78 hours + 1.56 hours = 3.23 hours

Therefore, the president will spend approximately 3.23 hours in the air during these business visits.

Please note that the flight time calculation does not include any additional time for takeoff, landing, or potential delays.
