One pipe fills a tank (5) hours faster than another pipe. Together they fill the tank in (6) hours. In how many hours will the faster pipe alone fill it?

Answer and explanation

Correct answer: (10) h

Let the faster pipe take (x) hours, so the slower takes (x+5). From (\frac{1}{x}+\frac{1}{x+5}=\frac{1}{6}), (x=10).
