Question

Скорость катера против течения реки равна 17,8км/ч,а собственная скорость катера -19,4км/ч.Найдите скорость катера по течению.

Answer 1

19,4-17,8 = 1,6 (ск. реки)
19,4 + 1,6 = 21 км/ч (ск. катера по течению)

Answer 2

Calculating Boat Speed in Still Water

To find the speed of the boat in still water when it's moving against the current, we can use the following formula:

Boat speed against the current = (Speed of the boat in still water) - (Speed of the current)

Given: - Speed of the boat against the current = 17.8 km/h - Speed of the boat in still water = 19.4 km/h

Using the formula, we can calculate the speed of the current:

Speed of the current = Speed of the boat in still water - Speed of the boat against the current Speed of the current = 19.4 km/h - 17.8 km/h Speed of the current = 1.6 km/h

Therefore, the speed of the current is 1.6 km/h.
