Question

В бассейне 200 метров кубических воды одновременно открыли две трубы через одну вода вливается со скоростью 30 метров кубических час через другую выливается со скоростью 10 метров кубических в час сколько воды будет в бассейне через 9 часов

Answer 1

Calculation of Water in the Pool

To calculate the amount of water in the pool after 9 hours, we need to consider the inflow and outflow rates of water.

According to the information provided, there are two pipes in the pool. One pipe pours water into the pool at a rate of 30 cubic meters per hour, while the other pipe drains water from the pool at a rate of 10 cubic meters per hour.

To determine the amount of water in the pool after 9 hours, we can calculate the net inflow of water by subtracting the outflow from the inflow.

The net inflow of water per hour can be calculated as follows: Inflow rate - Outflow rate = Net inflow rate

Substituting the given values: 30 cubic meters per hour - 10 cubic meters per hour = 20 cubic meters per hour

Now, we can calculate the total amount of water in the pool after 9 hours by multiplying the net inflow rate by the number of hours: Net inflow rate * Number of hours = Total amount of water

Substituting the values: 20 cubic meters per hour * 9 hours = 180 cubic meters

Therefore, after 9 hours, there will be 180 cubic meters of water in the pool.
