Question

Бассейн наполняется водой через две трубы за 6 часов если вода поступает в бассейн только из первой трубы то он наполнится за 10 часов . за какое время наполнится бассейн если вода будет поступать только из второй трубы

Answer 1

1) 1/6 - 1/10 = 5/30 - 3/30 = 2/30 = 1/15 производительность второй трубы
2) 1 : 1/15 = 15 часов за столько наполнит бассейн только вторая труба

Answer 2

Problem Analysis

The problem states that a pool is filled with water through two pipes in 6 hours. If the water flows into the pool only through the first pipe, it will be filled in 10 hours. We need to find out how long it will take to fill the pool if the water flows only through the second pipe.

Solution

Let's denote the rate of the first pipe as x and the rate of the second pipe as y. We know that both pipes together can fill the pool in 6 hours, so their combined rate is: 1/6 = x + y When only the first pipe is used, the pool is filled in 10 hours, so the rate of the first pipe is: 1/10 = x We need to find the time it takes to fill the pool using only the second pipe, so we need to find the rate of the second pipe.

Calculating the Rate of the Second Pipe

We can use the information from the first two equations to find the rate of the second pipe.

From equation 1/6 = x + y

From equation 1/10 = x

By substituting the value of x from equation into equation we can solve for y.

Calculating the Time to Fill the Pool with the Second Pipe

Once we have the rate of the second pipe, we can use it to calculate the time it takes to fill the pool using only the second pipe.

Final Answer

The time it will take to fill the pool if the water flows only through the second pipe can be calculated using the rate of the second pipe.

Let's proceed with the calculations.
