Question

За 6 ч труба перекачивает 9м³ воды сколько кубических метров воды перекачала та труба за 14 часов работы

Answer 1

Ответ:

Пошаговое объяснение:

за 6 часов - 9 м³

делим все на 3 и получаем:

за 2 часа - 3 м³

умножаем все на 7 и получаем:

за 14 часов - 21 м³

Answer 2

To find out how many cubic meters of water the pipe has pumped in 14 hours, we can set up a proportion using the given information:

Rate of pumping = Volume of water / Time

Let x be the volume of water pumped in 14 hours. We know that the rate of pumping is 9 m³ in 6 hours, so we can write:

9 m³ / 6 hours = x m³ / 14 hours

To find x, we can cross-multiply and solve for it:

6 hours * x m³ = 9 m³ * 14 hours 6x = 126

Now, solve for x:

x = 126 / 6 x = 21

So, the pipe has pumped 21 cubic meters of water in 14 hours.
