Question

Ребята, срочно!!!Вычислить протяженность Австралии а)в градусах, перевести в км, б)в см, перевести в км при помощи масштабав км по 140 в.д, масштаб 1:28500000

Answer 1

А)40°, значит 40×111=4440км
б)15 см, значит 28500000×15=427500000см=4275 км

Answer 2

Calculating the Length of Australia

To calculate the length of Australia, we can use the given scale of 1:28,500,000 and the longitude coordinates of 140°E. Let's break down the calculation into two parts:

a) Converting degrees to kilometers: To convert the length of Australia from degrees to kilometers, we need to know the distance covered by one degree of longitude at the given latitude. The distance covered by one degree of longitude varies depending on the latitude. At the equator, one degree of longitude is approximately 111 kilometers. However, as we move away from the equator, the distance covered by one degree of longitude decreases.

Unfortunately, the search results did not provide the specific latitude for which we need to calculate the length of Australia. Therefore, it is not possible to provide an accurate conversion from degrees to kilometers without this information.

b) Converting degrees to centimeters and then to kilometers using the given scale: To convert the length of Australia from degrees to centimeters, we can use the fact that one degree of longitude is approximately 111,319.9 kilometers at the equator. We can then convert centimeters to kilometers using the given scale of 1:28,500,000.

However, since we do not have the specific latitude for which we need to calculate the length of Australia, we cannot provide an accurate conversion from degrees to centimeters and then to kilometers without this information.

In conclusion, without the specific latitude for which we need to calculate the length of Australia, it is not possible to accurately determine the length of Australia in kilometers or centimeters using the given information.
