Problema Solution
two pipes are connected to the same tank. when working together, they can fill the tank in 2 hrs. the larger pipe, working alone, can fill the tank in 3 hrs less time than the samller one. how long would the smaller one take, working alone, to fill the tank?
Answer provided by our tutors
both takes 2 hours to fill so they fill 1/2 in an hour
larger fills in 3 hours so in 1 hour it fills =1/3
smaller pipe fills in 1 hour =1/2 -1/3=1/6
so smaller will fill in 6 hours.
