Question

Скорость катера по течению реки 24 км ч а против течения 20 км ч Найдите собственную скорость катера

Answer 1

(24 - 20 ) : 2 = 2 км/ч - скорость течения.
24 - 2 = 22 км/ч - собственная скорость катера.

Answer 2

Х - скорость катера
у - скорость течения
составляем систему уравнений:
х+у=24
х-у=20
решаем систему:
х=20+у
20+у+у=24
2у=4
у=4/2
у=2 км/ч - скорость течения
х=20+2=22 км/ч - скорость течения

Answer 3

Calculation of the Boat's Speed

To find the boat's own speed, we need to subtract the speed of the river's current from the boat's speed when going against the current.

Given: - Speed of the boat in still water (own speed): unknown - Speed of the boat when going with the current: 24 km/h - Speed of the boat when going against the current: 20 km/h

To calculate the boat's own speed, we can use the following formula:

Own Speed = Speed with Current - Speed against Current

Substituting the given values:

Own Speed = 24 km/h - 20 km/h

Simplifying the equation:

Own Speed = 4 km/h

Therefore, the boat's own speed is 4 km/h.
