Question

Скорость катера по течению реки равна 19 км/ч,а скорость течения 2км/ч. Найдите скорость катера против течения.Помогите!!!!

Answer 1

19 = Х + 2 
Х = 19 - 2 
Х = 17 ( км/час )
ОТВЕТ 17 км/час 

Answer 2

Скорость против течения = 19-2=17 км/ч

Answer 3

Calculating Boat Speed Against the Current

To find the speed of the boat against the current, we can use the formula: boat speed against the current = boat speed in still water - current speed.

Given: - Boat speed in still water (V) = 19 km/h - Current speed (Vc) = 2 km/h

Using the formula: Boat speed against the current = 19 km/h - 2 km/h = 17 km/h.

This means the speed of the boat against the current is 17 km/h.

Therefore, the speed of the boat against the current is 17 km/h.
