Question

Теплоход проходит расстояние между пристанями B и C по течению за 6ч а обратно против течения за 8 ч . Сколько времени понадобиться плоту что бы проплыть расстояние от B до C

Answer 1

Скорость теплохода в стоячей воде х, реки у, время плота t
Приравниваем пути теплохода от А до В и обратно
6(x+y)=8(x-y)
14y=2x
x=7y

Приравниваем пути от А до В теплохода и плота
6(x+y)=ty
48y=ty
t=48

Answer 2

Calculation of Time Required for the Boat to Travel from B to C

To calculate the time required for the boat to travel from point B to point C, we need to consider the time it takes for the boat to travel with the current and against the current.

According to the given information, the boat takes 6 hours to travel from B to C with the current and 8 hours to travel from C to B against the current.

Let's assume the speed of the boat in still water as x and the speed of the current as y.

When the boat is traveling with the current, the effective speed of the boat is the sum of its speed in still water and the speed of the current. Therefore, the boat's speed from B to C is (x + y).

Similarly, when the boat is traveling against the current, the effective speed of the boat is the difference between its speed in still water and the speed of the current. Therefore, the boat's speed from C to B is (x - y).

We can set up the following equation based on the given information:

Distance from B to C = (x + y) * 6

Distance from C to B = (x - y) * 8

To find the value of x and y, we need additional information or equations. Unfortunately, the given information is not sufficient to determine the exact values of x and y.

Therefore, without additional information, we cannot calculate the exact time required for the boat to travel from B to C.
