Question

В бассейн проведено 3 трубы. По 2 трубам вода поступает в бассейн,а по 3 вытекает.1 труба наполняет бассейн водой за 6 часов ,а 2 за 8 часов.По 3 трубе вода из наполненного бассейна вытекает за 4 часа полностью.Какая часть обьёма бассейна наполнется водой за час,если вода течет одновременно по 3 трубам?

Answer 1

1/6+1/8-1/4=4/24+3/24-6/24=1/24 мне тож так кажеться как написала та девочка как називаеться забыл

 

Answer 2

1/6+1/8-1/4=4/24+3/24-6/24=1/24

Answer 3

Problem Analysis

We have a pool with three pipes. Two pipes fill the pool with water, while the third pipe drains the water from the filled pool. We are given the time it takes for each pipe to fill the pool and drain the water. We need to determine the fraction of the pool that will be filled with water in one hour when all three pipes are running simultaneously.

Solution

To find the fraction of the pool that will be filled with water in one hour, we need to calculate the total volume of water that enters the pool in one hour and divide it by the volume of the pool.

Let's calculate the volume of water that enters the pool in one hour through each pipe:

- Pipe 1 fills the pool in 6 hours, so in one hour, it fills 1/6th of the pool's volume. - Pipe 2 fills the pool in 8 hours, so in one hour, it fills 1/8th of the pool's volume. - Pipe 3 drains the water from the filled pool in 4 hours, so in one hour, it drains 1/4th of the pool's volume.

To find the total volume of water that enters the pool in one hour when all three pipes are running simultaneously, we add the volumes filled by each pipe and subtract the volume drained by Pipe 3:

Volume filled in one hour = (1/6) + (1/8) - (1/4)

Now, let's calculate the fraction of the pool that will be filled with water in one hour:

Fraction filled in one hour = Volume filled in one hour / Volume of the pool

Calculation

To perform the calculation, we need to know the volume of the pool. Unfortunately, the volume of the pool is not provided in the question. Could you please provide the volume of the pool?
