Question

Протяженность железной дороги Москва - Санкт Петербург равна 650 км. Эта дорога изображена линией на карте в маштабе 1: 2500000. Найдите длину линии изображающей дорогу. Ответ дайте в сантиметрах.

Answer 1

650 нужно перевести в сантиметры, переводим 650 км, 650000 м, 65000000 см.
65000000:2500000=26(см)
Ответ:26 см длина линии изображающую дорогу.

Answer 2

Length of the Railway Line on the Map

To find the length of the railway line representing the distance between Moscow and St. Petersburg on a map with a scale of 1:2,500,000, we can use the concept of map scales.

The scale of 1:2,500,000 means that one unit on the map represents 2,500,000 units in reality. In this case, the units on the map are not specified, but we can assume that they are centimeters.

Given that the actual distance between Moscow and St. Petersburg is 650 km, we need to calculate the length of the line on the map.

To do this, we can set up the following proportion:

1 cm on the map / 2,500,000 cm in reality = x cm on the map / 650,000 cm in reality

Solving for x, we find:

x = (1 cm on the map * 650,000 cm in reality) / 2,500,000 cm in reality

Calculating this expression, we get:

x ≈ 0.26 cm

Therefore, the length of the line representing the Moscow-St. Petersburg railway on the map is approximately 0.26 centimeters.

Please note that the sources provided did not directly answer the question, but the calculation is based on the concept of map scales and proportional reasoning.
