Question 611009: Hose A can fill a water tank in 14 hours, while Hose B can fill the same tank in 20 hours. How long will it take to fill the tank if both hoses are used? This needs to be written as a linear equation.
What I have tried:
X= Hose A which fills 1/14 of the tank in an hour
Y= Hose B which fills 1/20 of the tank in an hour
X+Y= (14+20)/20*14= 34/280= 17/140
This is as far as I got but my answer would be 17 hours which is incorrect.
Thank you
