a pipe fill a tank in 3hrs.another pipe fill that same tank
in 2hrs.if both pipe inserted in tank to fill it how timw it
will take to fill?
Answer Posted / marktopher
This seems too easy, maybe I'm missing something?
But if the smaller pipe fills the tank in 2 hours, adding a
2nd larger pipe will only reduce that time, so right off
the start, we know that the answer is less than 2 hours
(120 min).
The answer I got is 1.2 hours (aka 1hr 12min, aka 72 min)
