Question

Два фильтра марки «Родник» очищают 1000 л воды за 5 часов. За сколько часов один такой фильтр очистит 600 л воды?

Answer 1

1) 1000 : 5 = 200 (л. воды в час)
2) 200 : 2 = 100 (один фильтр)
3) 600 : 100 = 6 (часов)
Ответ: 6 часов понадобится на то, что бы один фильтр очистил 600л. воды.

Answer 2

Calculating Water Filtration Time

To calculate how long it takes for one "Rodnik" filter to purify 600 liters of water, we can use the information provided that two filters purify 1000 liters of water in 5 hours.

Step 1: Calculate the purification rate of two filters. The combined purification rate of two filters can be calculated using the given information: - Two filters purify 1000 liters of water in 5 hours.

Step 2: Calculate the purification rate of one filter. Once we have the combined purification rate of two filters, we can find the purification rate of one filter by dividing the combined rate by 2.

Step 3: Calculate the time taken for one filter to purify 600 liters of water. Using the purification rate of one filter, we can calculate the time it takes for one filter to purify 600 liters of water.

Let's proceed with the calculations.

Step 1: The combined purification rate of two filters can be calculated as follows: - Combined purification rate = Total liters of water purified / Total time taken - Combined purification rate = 1000 liters / 5 hours - Combined purification rate = 200 liters/hour

Step 2: The purification rate of one filter can be found by dividing the combined rate by 2: - Purification rate of one filter = Combined purification rate / 2 - Purification rate of one filter = 200 liters/hour / 2 - Purification rate of one filter = 100 liters/hour

Step 3: Now, we can calculate the time taken for one filter to purify 600 liters of water: - Time taken = Total liters of water / Purification rate of one filter - Time taken = 600 liters / 100 liters/hour - Time taken = 6 hours

Conclusion: Therefore, one "Rodnik" filter will purify 600 liters of water in 6 hours.
