Two pipes running together can fill a pipe in 11 1/9 minutes. if one pipe takes 5 mins more than the other to fill the tank separately,find the time in

which each pipe would fill the tank separately.


11 1/9=100/9

first pipe want x m  to fill the tank
second tap want x+5 m to fill the tank

amount of water that fill through the 1st pipe in 1 miniute= \frac{1}{x}

 \frac{1}{x} + \frac{1}{x+5} = \frac{100}{9}  \\  \\ 
 \frac{x+5+x}{ x^{2} +5x}= \frac{100}{9}   \\  \\ 
18x+45=100 x^{2} +500x \\  \\ 
100 x^{2} +500x-18x=45 \\ 
100 x^{2} +482x=45 \\ 
100 x^{2} +482x-45=0

then factor it ..

1 5 1
i guess it should be 481x
no how?
plz pick it as the best..
