One pipe can fill the pool in 5 hours and the other in twice as long, after how many hours the entire pool

One pipe can fill the pool in 5 hours and the other in twice as long, after how many hours the entire pool will be filled if you open two pipes; which part of the pool will be filled in two hours?

1. Find out how many hours it will take for the second pipe to fill the pool, if we know that it fills the pool 2 times longer than the first pipe.

5 * 2 = 10 hours.

2. If the first pipe can fill the pool in 5 hours, then in 1 hour, it will fill 1/5 of the pool.

3. If the second pipe can fill the pool in 10 hours, then in 1 hour, it will fill 1/10 of the pool with water.

4. Now let’s find out which part of the pool both pipes can fill in 1 hour. To do this, you need to fold both parts.

1/5 + 1/10 = 2/10 + 1/10 = 3/10 of the pool.

5. Find out which part of the pool both tubes will fill in 2 hours. To do this, multiply the part of the pool that the tubes fill in 1 hour by 2.

3/10 * 2 = 6/10 part of the pool.

6. Let’s calculate how long it takes both pipes to fill the entire pool. The whole pool is a whole unit.

1/3/10 = 1 * 10/3 = 10/3 = 3 1/3 hours.

Answer: Both pipes will fill the pool in 3 1/3 hours. In 2 hours they will fill 6/10 of the pool.
