Question

2 одинаковые гигантские устрицы,добывая себе пищу, отфильтровали 120 литров воды. одна из них добывала корм 5 часов, а другая 3 ч. сколько литров воды отфильтровала каждая устрица?

Answer 1

Если их скорость одинакова, то:
120÷(5+3)=15 литров за час фильтрует устрица
15×5=75литров воды отфильтровала первая устрица
15×3=45литров вторая устрица

Answer 2

Calculation of Water Filtered by Each Oyster

To calculate the amount of water filtered by each oyster, we need to know the total amount of water filtered and the time each oyster spent filtering.

According to the information provided, two identical giant oysters filtered 120 liters of water. One oyster filtered for 5 hours, while the other filtered for 3 hours.

To find out how much water each oyster filtered, we can use the formula:

Amount of water filtered = Total amount of water / Total time

Let's calculate the amount of water filtered by each oyster:

For the oyster that filtered for 5 hours: Amount of water filtered = 120 liters / 5 hours = 24 liters per hour.

For the oyster that filtered for 3 hours: Amount of water filtered = 120 liters / 3 hours = 40 liters per hour.

Therefore, the oyster that filtered for 5 hours filtered 24 liters of water, while the oyster that filtered for 3 hours filtered 40 liters of water.
