Question

Длина реки Дон 1870 км,при этом судоходная часть больше несудоходной на 840 км.Определите длину судоходноой части Дона?

Answer 1

Х - несудоходная часть
(х+840) +х = 1870
2х = 1870-840
2х = 1030
х = 515 км

Судоходная: 515+840=1355 км
Ответ: 1355 км

Answer 2

Calculating the Length of the Navigable Part of the Don River

The total length of the Don River is 1870 km, with the navigable part being 840 km longer than the non-navigable part. To determine the length of the navigable part, we can use the following calculation:

1. Total Length of the Navigable Part: - Total Length of the Don River: 1870 km - Length of the Non-Navigable Part: x km - Length of the Navigable Part: x + 840 km

Using this information, we can calculate the length of the navigable part of the Don River.
