Question

Лодка шла по течению со скоростью 12.6 км ч а против течения 8.8 км ч . найдите скорость течения зная что собственная скорость лодки не изменялась. пожалуйста

Answer 1

12.6-8.8= 3.8 (км/ч)

Answer 2

Calculating River Current Speed

To find the speed of the river current, we can use the formula: Boat's speed downstream - Boat's speed upstream = 2 * River current speed

Given: - Boat's speed downstream (with the current) = 12.6 km/h - Boat's speed upstream (against the current) = 8.8 km/h

Using the formula: 12.6 - 8.8 = 2 * River current speed

Calculating River Current Speed

River current speed = (12.6 - 8.8) / 2

Applying the values: River current speed = (12.6 - 8.8) / 2 = 3.8 / 2 = 1.9 km/h

So, the speed of the river current is 1.9 km/h.
