Question

Скорость катера по течению реки 22 км в час, а против течения 18 км в ч. Найдите скорость течение реки и собственную скорость катера? Помогите срочно!!!

Answer 1

Скорость катера - 20км/ч
20+2=22км/ч по течение
20-2=18км/ч против течения.
-----------------------------------------------

Answer 2

1) 22-18=4 км/ч- их разница
2) 4:3=2 км/ч- скорости течения
3) 22-2=20 км/ч- скорость катера

Answer 3

Calculation of River Current Speed and Boat's Speed

To find the speed of the river current and the boat's own speed, we can use the following formula:

Boat's Speed = (Speed Downstream + Speed Upstream) / 2 River Current Speed = (Speed Downstream - Speed Upstream) / 2

Given that the boat's speed downstream is 22 km/h and the boat's speed upstream is 18 km/h, we can substitute these values into the formulas to find the river current speed and the boat's own speed.

Boat's Speed = (22 + 18) / 2 = 40 / 2 = 20 km/h River Current Speed = (22 - 18) / 2 = 4 / 2 = 2 km/h

Therefore, the boat's own speed is 20 km/h and the speed of the river current is 2 km/h.
