Question

Расстояние между Санкт-Петербургом и Москвой по прямой составляет 634 км. Сколько сантиметров составит расстояние между соответствующими точками на карте с масштабом 1:20 000 000? Ответ округли до десятых. СРОЧНО +50 БАЛЛОВ ДАМ!

Answer 1

Ответ:3,2см

Пошаговое объяснение:

634км=63400000см

63400000÷20 000 000=3,17см=3,2см

Answer 2

Ответ:

Пошаговое объяснение:

634 км = 63400000 см

х = расстояние на карте

х/63400000 = 1/20000000

х = 63400000 * 1 / 20000000

х = 63400000/20000000

х = 3,17

х ≈ 3,2

Ответ: 3,2 см

Answer 3

Calculation of the Distance on the Map

To calculate the distance between two points on a map with a given scale, we can use the concept of map scale. The map scale represents the ratio of the distance on the map to the actual distance on the ground. In this case, the scale is given as 1:20,000,000, which means that 1 unit on the map represents 20,000,000 units in reality.

Given that the straight-line distance between St. Petersburg and Moscow is 634 km, we can calculate the corresponding distance on the map using the scale.

To find the distance on the map, we can set up the following proportion:

1 unit on the map / 20,000,000 units in reality = x units on the map / 634 km

Simplifying the proportion, we get:

x = (1 / 20,000,000) * 634 km

Calculating this expression, we find:

x ≈ 0.0000317 km

To convert this distance to centimeters, we can multiply it by 100,000 (since there are 100,000 centimeters in a kilometer):

0.0000317 km * 100,000 cm/km ≈ 3.17 cm

Therefore, the distance between the corresponding points on the map with a scale of 1:20,000,000 is approximately 3.17 centimeters.

Please note that the provided sources did not directly answer the question, but the calculation is based on the concept of map scale and the given distance between St. Petersburg and Moscow.
