Question

Скорость катера в стоячей воде 12,3 км/ч. Скорость течения реки 2,8 км/ч. Найдите скорость катера против течения реки. 34 бала))

Answer 1

Ответ:9,5км/ч(скорость катера вычесть скорость течения)

Answer 2

1) 12,3 – 2,8 = 9,5 (км/ч) – скорость катера против течения.

Answer 3

Calculating Boat Speed Against River Current

To find the speed of the boat against the river current, we can use the formula:

Boat speed against current = Boat speed in still water - River current speed

Given: - Boat speed in still water = 12.3 km/h - River current speed = 2.8 km/h

Using the formula: Boat speed against current = 12.3 km/h - 2.8 km/h = 9.5 km/h

Therefore, the speed of the boat against the river current is 9.5 km/h.
