Question

Власна швидкість катера дорівнює 32,5 км/год знайдіть швидкість катера за течією річки, якщо його швидкість проти течії річки становить 29,3 км/год. СРОЧНО!!!!!!!!!!!!

Answer 1

Ответ:

35,7 км/ч — скорость катера по течению реки

Пошаговое объяснение:

пусть скорость реки будет х, тогда (32,5 - х) — это скорость катера против течения реки, а (32,5 + х) — скорость катера по течению реки. Составим и решим уравнение!

32,5 - х = 29,3

х = 32,5 - 29,3

х = 3,2 — скорость течения реки, тогда 32,5 + 3,2 = 35,7 км/ч — скорость катера по течению реки

Answer 2

To find the speed of the boat with the current of the river, we can use the concept of relative velocity. The speed of the boat with the current can be calculated by adding the speed of the boat against the current to the speed of the current itself.

Given: - Speed of the boat in still water (against the current): 29.3 km/h - Speed of the current: unknown - Speed of the boat with the current: 32.5 km/h

Let's assume the speed of the current is represented by 'x' km/h.

Using the concept of relative velocity, we can set up the following equation:

Speed of the boat with the current = Speed of the boat against the current + Speed of the current

32.5 km/h = 29.3 km/h + x km/h

To find the value of 'x', we can subtract 29.3 km/h from both sides of the equation:

32.5 km/h - 29.3 km/h = x km/h

Simplifying the equation:

3.2 km/h = x km/h

Therefore, the speed of the current is 3.2 km/h.

Please note that this calculation assumes a linear relationship between the speed of the boat and the speed of the current. In reality, the relationship may be more complex and affected by various factors.
