Ответ:

за 39 минут можно заполнить бассейн с помощью 6 таких труб

Пошаговое объяснение:

Это обратно пропорциональная зависимость двух величин, при которой уменьшение одной величины приводит к пропорциональному увеличению другой и наоборот.

↓9 тр. - 26 минут↑

↓6 тр. - х минут↑

9 : 6 = х : 26

6х = 234

х = 234/6

х = 39 (минут) - за 39 минут можно заполнить бассейн с помощью 6 таких труб
