Question

Скорость моторной лодки по течению 28 км/ч,а против течения 23км/ч.Какова скорость течения реки?

Answer 1

От скорости по течению вычитаем скорость против течения :
28-23=5 км/ч

Answer 2

1) 28-23=5 (км/ч) - скорость реки, умноженная на два.
2) 5:2 = 2,5 (км/ч) - скорость течения реки.

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 motorboat against the current is 23 km/h and the speed of the motorboat with the current is 28 km/h, we can substitute these values into the formula:

River Current Speed = 28 km/h - 23 km/h

Calculating this, we find that the speed of the river current is 5 km/h.

Please note that the information provided is based on the given values and the calculation method described above.
