Question

В час первая труба наполняет 1/40 бассейна, а вторая 1/60 .какую часть бассейна наполняют за 1час две трубы вместе? за сколько часов наполнится весь бассейн, если открыть обе трубы?

Answer 1

1)1/40+1/60=1/24басейна-две трубы за один час

2)24/1=24часа-наполнится басейн

Answer 2

Calculation of the Fraction of the Pool Filled in One Hour

To determine the fraction of the pool that is filled in one hour when both pipes are open, we need to add the rates at which each pipe fills the pool.

The first pipe fills 1/40 of the pool in one hour, and the second pipe fills 1/60 of the pool in one hour.

To find the combined rate, we add the rates of the two pipes:

1/40 + 1/60 = 3/120 + 2/120 = 5/120

Therefore, the two pipes together fill 5/120 of the pool in one hour.

Calculation of the Time to Fill the Entire Pool

To calculate the time it takes to fill the entire pool, we need to determine how many times the combined rate fills the pool in one hour.

Since the combined rate is 5/120, we can calculate the number of times it fills the pool in one hour by dividing 1 by 5/120:

1 ÷ (5/120) = 120/5 = 24

Therefore, the two pipes together fill the entire pool in 24 hours.

Summary: - The two pipes together fill 5/120 of the pool in one hour. - It takes 24 hours for the two pipes to fill the entire pool.
