Question

Насос накачивает в резервуар 150 л воды в час. Затем вода проходит через фильтр со скоростью 80 л в час и скапливается в центре. Сколько не очищенной воды останется в результате через 6 ч работы насоса?

Answer 1

150 × 6= 900 л
900÷80= 11 ост 20 л

Answer 2

150*6=900л воды накачал насос за 6 часов
80*6=480л очищенной воды прошло через фильтр
900-480=420 л неочищенной воды осталось в резервуаре
Ответ: 420 литров

Answer 3

Calculation of Remaining Unclean Water

To calculate the amount of unclean water remaining after 6 hours of the pump's operation, we need to consider the flow rates of the pump and the filter.

The pump inflows 150 liters of water per hour into the reservoir After 6 hours, the pump would have pumped a total of 150 liters/hour * 6 hours = 900 liters of water into the reservoir.

The filter processes water at a rate of 80 liters per hour Therefore, after 6 hours, the filter would have processed a total of 80 liters/hour * 6 hours = 480 liters of water.

To calculate the remaining unclean water, we subtract the amount of water processed by the filter from the total amount of water pumped into the reservoir:

900 liters (total pumped) - 480 liters (processed by filter) = 420 liters of unclean water remaining in the reservoir after 6 hours of the pump's operation.

Therefore, after 6 hours of the pump's operation, there would be 420 liters of unclean water remaining in the reservoir.
