Question

Собственная скорость лодки 3,4 км/ч. Скорость лодки против течения реки 0,8 км/ч. Найдите скорость лодки по течению.

Answer 1

3,4-0,8=2,6 скорость течения 3,4+2,6=6 скорость лодки по течению

Answer 2

3,4 - 0,8 = 2,6 (км/ч) - скорость течения реки.
3,4 + 2,6 = 6 (км/ч) - скорость лодки по течению реки.
Ответ: 6 км/ч.

Answer 3

Calculation of Boat Speed in Still Water

To find the speed of the boat in still water, we need to subtract the speed of the current from the boat's actual speed. In this case, the boat's speed is given as 3.4 km/h, and the speed of the current is 0.8 km/h.

Therefore, the speed of the boat in still water can be calculated as:

Boat Speed in Still Water = Boat Speed - Speed of Current

Boat Speed in Still Water = 3.4 km/h - 0.8 km/h

Boat Speed in Still Water = 2.6 km/h.

So, the speed of the boat in still water is 2.6 km/h.
