Question

Катер прошел 192 км против течения реки за 6 часов. найдите скорость течения реки,если скорость катера в стоячей воде равна 35 км/ч

Answer 1

Пусть х км/ч - скорость течения реки.
Тогда (35 - х) км/ч - скорость против течения реки,
         (35 - х) * 6 км -весь пройденный путь.
Так как по условию задачи катер всего прошел 192 км, составим и решим уравнение:
(35 - х) * 6 = 192
35 - х = 32
х = 4
Ответ: 3 км/ч - скорость течения реки

Answer 2

1) Находим скорость катера против течения: 192 : 6=32км/ч
2) Скорость катера в стоячей воде равна 35км/ч. Значит, скорость течения равна: 35 - 32 = 3км/ч. ;-)

Answer 3

Calculation of River Current Speed

To find the speed of the river current, we can use the formula:

Speed of the boat in still water = Speed of the boat against the current + Speed of the current

Given that the speed of the boat in still water is 35 km/h and the boat traveled 192 km against the current in 6 hours, we can set up the equation as follows:

35 km/h = Speed of the boat against the current + Speed of the current

We need to find the speed of the current.

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

The speed of the boat against the current is the difference between the speed of the boat in still water and the speed of the current:

Speed of the boat against the current = 35 km/h - x km/h

According to the given information, the boat traveled 192 km against the current in 6 hours. We can use the formula:

Distance = Speed × Time

192 km = (35 km/h - x km/h) × 6 hours

Now, we can solve this equation to find the speed of the current.

192 km = (35 km/h - x km/h) × 6 hours

Dividing both sides of the equation by 6:

32 km = 35 km/h - x km/h

Rearranging the equation:

x km/h = 35 km/h - 32 km

Simplifying:

x km/h = 3 km/h

Therefore, the speed of the river current is 3 km/h.
