Mokri banditi | The Wet Bandits #2

Drugom prilikom Harry i Marv nisu uspjeli u potpunosti zatvoriti odvod. Tako su bile otvorene tri slavine, jedna bi sama poplavila kuću za 3 sata, druga za 5 sati, a treća za 8, ali je voda curila kroz odvod koji bi sam ispraznio poplavljenu kuću za 7 sati. Za koliko sati će se kuća poplaviti?

Another time, Harry and Marv didn't manage to plug the drain completely. They then turned on three faucets: the first one would flood the house on its own in 3 hours, the second one in 5 hours, and the third one in 8 hours. However, water was also leaking through the drain, which would drain a flooded house completely in 7 hours. How many hours will it take for the house to become fully flooded?
