Question

"Вычислите длину Африки в градусах и километрах с севера на юг по меридиану 20° в.д. и с запада на восток вдоль Северного тропика,экватора и Южного тропика. (Протяженность 1° по меридиану и экватору составляет 111 км,по тропикам-102,5 км.)" Прошу.Очень нужно))))

Answer 1

Ояние с севера на юг по 20 меридиану в градусах и км

32 ° + 37 ° = 69° (в градусах)

69° х 111 = 7659 (км)

Чтобы найти протяженность материка с севера на юг в километрах, умножьте полученное количество градусов на 111 км (именно столько километров в одном градусе по меридиану) .

Answer 2

Calculating the Length of Africa

To calculate the length of Africa in degrees and kilometers, we need to consider the distance from north to south along the 20° E meridian and from west to east along the Northern Tropic, Equator, and Southern Tropic.

The length of 1° along the meridian and the Equator is given as 111 km, while along the tropics, it is 102.5 km.

Let's calculate the length of Africa in degrees and kilometers:

1. Length from North to South along the 20° E Meridian: - The length of 1° along the meridian is 111 km. - To calculate the length of Africa in degrees, we need to find the difference in latitude between the northernmost and southernmost points of Africa along the 20° E meridian. - Unfortunately, the exact coordinates of the northernmost and southernmost points along the 20° E meridian are not provided in the search results. - Therefore, we cannot calculate the length of Africa from north to south along the 20° E meridian.

2. Length from West to East along the Northern Tropic, Equator, and Southern Tropic: - The length of 1° along the tropics is 102.5 km. - To calculate the length of Africa in degrees, we need to find the difference in longitude between the westernmost and easternmost points of Africa along the Northern Tropic, Equator, and Southern Tropic. - Unfortunately, the exact coordinates of the westernmost and easternmost points along these lines are not provided in the search results. - Therefore, we cannot calculate the length of Africa from west to east along the Northern Tropic, Equator, and Southern Tropic.

In conclusion, without the specific coordinates of the northernmost, southernmost, westernmost, and easternmost points of Africa along the 20° E meridian and the tropics, we cannot accurately calculate the length of Africa in degrees and kilometers.

Please note that the search results did not provide the necessary information to calculate the length of Africa.
