Question

Бассейн заполняется через 2 трубы за 6 ча сов.Если вода поступает в бассейн только из первой трубы,то он наполняется за 10 часов . За какое время наполняется бассейн, если вада паступает только из второй трубы?

Answer 1

30 будет по моему как я посчитала у нас такая задача уже была

Answer 2

Problem Analysis

We are given that a pool is being filled by two pipes together in 6 hours. If the pool is filled only by the first pipe, it takes 10 hours to fill. We need to determine how long it takes to fill the pool if only the second pipe is used.

Solution

Let's assume that the first pipe can fill the pool in x hours, and the second pipe can fill the pool in y hours.

From the given information, we know that: - Both pipes together can fill the pool in 6 hours. - The first pipe alone can fill the pool in 10 hours.

Using this information, we can set up the following equations:

Equation 1: 1/x + 1/y = 1/6 (Both pipes together can fill the pool in 6 hours)

Equation 2: 1/x = 1/10 (The first pipe alone can fill the pool in 10 hours)

To find the time it takes to fill the pool using only the second pipe, we need to solve Equation 1 for y.

Calculation

Let's solve the equations to find the values of x and y.

From Equation 2, we have: 1/x = 1/10

Simplifying Equation 2, we get: x = 10

Substituting the value of x into Equation 1, we have: 1/10 + 1/y = 1/6

Multiplying both sides of the equation by 60y, we get: 6y + 60 = 10y

Rearranging the equation, we have: 4y = 60

Dividing both sides of the equation by 4, we get: y = 15

Therefore, the second pipe alone can fill the pool in 15 hours.

Answer

If the pool is filled only by the second pipe, it will take 15 hours to fill the pool.
