Question

Первая трубы пропускает на 15 литров воды в минуту меньше, чем вторая труба . Сколько литров воды в минуту пропускает первая труба, если резервуар объемом 100 литров она заполняет на 6 минут дольше, чем вторая труба?

Answer 1

Х-пропускает 1,х+15-пропускает 2
100/х-100/(х+15)=6
6х²+90х-100(х+15-х)=0
6х²+90х-1500=0
х²+15х-250=0
х1+х2=-15 и х1*х2=-250
х1=-25не удов усл
х2=10л пропускает 1 труба в минуту

Answer 2

Calculating Water Flow Rate for the First Pipe

To calculate the water flow rate for the first pipe, we can use the information provided in the question and the search results.

Given: - The first pipe passes 15 liters of water per minute less than the second pipe. - The first pipe fills a 100-liter reservoir 6 minutes longer than the second pipe.

Let's denote the water flow rate of the second pipe as x liters per minute.

The water flow rate of the first pipe can be expressed as (x - 15) liters per minute based on the given information.

Using the Reservoir Filling Time Difference

The time it takes for the first pipe to fill the 100-liter reservoir can be expressed as (100 / (x - 15)) minutes.

The time it takes for the second pipe to fill the same reservoir is (100 / x) minutes.

Given that the first pipe fills the reservoir 6 minutes longer than the second pipe, we can set up the equation:

(100 / (x - 15)) = (100 / x) + 6

Solving for x

We can solve the equation to find the value of x, which represents the water flow rate of the second pipe.

Let's solve the equation: ``` (100 / (x - 15)) = (100 / x) + 6 ```

By solving the equation, we can find the value of x, which will allow us to calculate the water flow rate for the first pipe.

Conclusion

By using the provided information and solving the equation, we can determine the water flow rate for the first pipe.
