I've been having trouble with the word questions in algebra. I do fine with the usual algebra questions, but for questions where you have to write the equation yourself, my mind just can't get around how. I'd like general advice on these questions, but I do have a specific one as well (which I'm sure will be obvious once I see the equation, haha):
"A high speed pump and a low speed pump can be used at the same time to fill a swimming pool in 8 hours. If only the low speed is used, it takes 3 hours longer than if only the high speed is used. How long does each pump take to fill the whole pool if used alone?"
I don't know where to even start writing the equation, I think there would be two equations and two variables, but I don't know...
Thank you very much.
