Question

a tank fills completely in 2 hours if both taps are open. if only one of the taps is open at the given time, the smaller tap takes 3 hours more than the larger one to fill the tank. how much time does each tap take to fill the tank completely?

Answer 1

x²+3x=4x+6
=>x²-x-6=0
=>x²-3x+2x-6=0
=>(x+2)(x-3)=0
so x=3 hours...
so smaller tap will take 6 hours
