Question

Базовые стоянки двух лагерей находится на реке скорость течения которой равна 4 км/ч. Турист из одного лагеря едет на катере в другой, а затем он возвращается обратно. В этот путь турист приезжает со средней скоростью 6 км/ч. Найди скорость катера.

Answer 1

Ответ:10км ч

Пошаговое объяснение:в одну сторону сопротивления нету а наоборот ускорение поэтому он едет 14 км в час а обратно есть сопротивление поэтому едет 6 км ч

Answer 2

Finding the Speed of the Boat

To find the speed of the boat, we can use the formula: speed = distance / time

The total distance traveled by the tourist is the sum of the distances traveled in each direction, and the total time is the sum of the times taken in each direction.

Let's denote the speed of the boat as x km/h, the speed of the river current as 4 km/h, and the speed of the tourist as 6 km/h.

Calculating the Speed of the Boat

The speed of the boat can be calculated using the formula: speed = distance / time

The speed of the boat in still water can be represented as: speed of boat = (speed of boat downstream + speed of boat upstream) / 2

The speed of the boat downstream can be represented as: speed of boat downstream = (speed of boat + speed of current)

The speed of the boat upstream can be represented as: speed of boat upstream = (speed of boat - speed of current)

Substituting the given values: 6 = (x + 4) / 2 12 = x + 4 x = 8

So, the speed of the boat is 8 km/h.
