Question

Бассейн вмещает 3600м2 воды. Он наполняется двумя трубами, включенными одновременно, за 12ч, а одной первой трубой за 20 ч. На сколько быстрее наполнит бассей одна первая труба, чем одна вторая?

Answer 1

2 труба заполнит быстрее на 8 часов

Answer 2

Calculation of Water Filling Rates

To determine how much faster the first pipe fills the pool compared to the second pipe, we need to calculate the filling rates of each pipe.

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

According to the given information: - When both pipes are turned on simultaneously, they fill the pool in 12 hours. - When only the first pipe is turned on, it takes 20 hours to fill the pool.

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

Equation 1: x + y = 12 (both pipes filling the pool in 12 hours) Equation 2: x = 20 (only the first pipe filling the pool in 20 hours)

To solve this system of equations, we can substitute Equation 2 into Equation 1:

20 + y = 12

Simplifying the equation, we find:

y = 12 - 20 = -8

However, it is not possible for the second pipe to fill the pool in negative time. Therefore, there seems to be an error in the given information or the problem statement.
