Question

Сумма длин трёх рек Таджикистана - Вахш, Хингоб и Шохдара - равна 866 км. Река Хингоб на 332 км короче реки Вахш и на 54 км длиннее Шохдары. Чему равна длина реки Хингоб?

Answer 1

Всего=866
пусть шохдара = х
хингоб = х+54
вахш = (х+54)+332

х+х+54+х+54+332=866
3х=866-332-54-54
3х=426
х=426/3
х=142(шохдара)
хингоб = 142+54=196

Answer 2

Length of the Hingob River

The sum of the lengths of the three rivers in Tajikistan, Vakhsh, Hingob, and Shokhdara, is 866 km. It is given that the Hingob River is 332 km shorter than the Vakhsh River and 54 km longer than the Shokhdara River.

To find the length of the Hingob River, we can use the information provided.

Given: - Sum of the lengths of the three rivers (Vakhsh, Hingob, and Shokhdara) = 866 km - Hingob River is 332 km shorter than the Vakhsh River - Hingob River is 54 km longer than the Shokhdara River

Calculation

Let's denote: - Length of the Vakhsh River as V - Length of the Hingob River as H - Length of the Shokhdara River as S

We know that: 1. V + H + S = 866 (Sum of the lengths of the three rivers) 2. H = V - 332 (Hingob River is 332 km shorter than the Vakhsh River) 3. H = S + 54 (Hingob River is 54 km longer than the Shokhdara River)

By substituting the value of H from equations 2 and 3 into equation 1, we can solve for the length of the Hingob River.

Solution

Substituting the value of H from equations 2 and 3 into equation 1: (V - 332) + (S + 54) + S = 866 V - 332 + S + 54 + S = 866 V + 2S - 278 = 866 V + 2S = 1144 V = 1144 - 2S

Now we have an equation in terms of V and S. However, we need more information to solve for the exact lengths of the rivers.

Unfortunately, the provided information is not sufficient to calculate the exact length of the Hingob River. Additional information about the length of at least one of the rivers (Vakhsh or Shokhdara) is needed to solve for the length of the Hingob River.
