Question

определи протяжённость Азии с севера в градусах и километрах на меридиану 90 градусов в.д.,используя только градусную сеть.Все вычисления проделай в развёрнутом виде.

Answer 1

протяженность азии с севера на юг по меридиану 90 градусов в.д. составляет 28 градусов.

мы знаем, что проятженность дуги в 1 градус на мередиане равна 111 км. следовательно 28*111=3108 км 

Answer 2

Determining the Length of Asia from North to South

To determine the length of Asia from north to south in degrees and kilometers along the meridian of 90 degrees east, we can use the following approach:

1. Convert Degrees to Kilometers: - The length of one degree of latitude is approximately 111 kilometers. - Therefore, to calculate the length in kilometers, we can simply multiply the number of degrees by 111.

2. Calculating the Length: - The distance from the North Pole to the South Pole along the 90th meridian can be calculated by subtracting the latitude of the North Pole from the latitude of the South Pole.

3. Conversion of Degrees to Kilometers: - Once we have the difference in degrees, we can convert it to kilometers using the conversion factor of 111 kilometers per degree.

Calculation

The latitude of the North Pole is 90 degrees, and the latitude of the South Pole is -90 degrees. Therefore, the difference in latitude is:

90° - (-90°) = 90° + 90° = 180°

Now, to convert this into kilometers:

180° * 111 km/° = 19,980 km

Therefore, the length of Asia from north to south along the 90th meridian is approximately 19,980 kilometers.
