Question

Помогите пожалуйста скорость течения реки 3 километров час на сколько километров в час скорость байдарки по течению больше чем против течения

Answer 1

Пусть ссобственная скорость байдарки - х.   ⇒
Скорость байдарки по течению реки  х+3, а против течения реки  x-3.
x+3-(x-3)=x+3-x+3=6
Ответ: скорость байдарки по течению реки на 6 км/ч больше скорости 
байдарки против течения реки.

Answer 2

Calculating Kayak Speed Relative to River Flow

To calculate the speed of a kayak relative to the flow of a river, we can use the following formula:

Speed of kayak with the flow of the river = Speed of kayak + Speed of river flow Speed of kayak against the flow of the river = Speed of kayak - Speed of river flow

Given that the speed of the river flow is 3 kilometers per hour, we can calculate the kayak's speed relative to the river flow.

Speed of Kayak with the Flow of the River

The speed of the kayak with the flow of the river is the sum of the speed of the kayak and the speed of the river flow.

Speed of kayak with the flow of the river = Speed of kayak + Speed of river flow Speed of kayak with the flow of the river = Speed of kayak + 3 kilometers per hour

Speed of Kayak against the Flow of the River

The speed of the kayak against the flow of the river is the difference between the speed of the kayak and the speed of the river flow.

Speed of kayak against the flow of the river = Speed of kayak - Speed of river flow Speed of kayak against the flow of the river = Speed of kayak - 3 kilometers per hour

Conclusion

To determine by how many kilometers per hour the speed of the kayak is greater when going with the flow of the river compared to going against the flow, we need the specific speed of the kayak. If you have the speed of the kayak, you can use the above formulas to calculate the exact difference in speed.
