Question

скорость лодки по течению реки 19 километра в час а против течения 13 литров в час Какова скорость течения реки

Answer 1

(19-13):2=3(км/ч) скорость течения

Answer 2

Если ты хотел написать 13 км\ч ,то тогда ответ: 3 км\ч . Так как 19-13=6 и 6:2=3 .

Answer 3

Calculation of River Current Speed

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

River Current Speed = Speed of Boat Upstream - Speed of Boat Downstream

Given that the speed of the boat upstream is 13 kilometers per hour and the speed of the boat downstream is 19 kilometers per hour, we can substitute these values into the formula:

River Current Speed = 19 km/h - 13 km/h

Simplifying the equation, we get:

River Current Speed = 6 km/h

Therefore, the speed of the river current is 6 kilometers per hour.
