If it has to do with a chapter on Rational Expressions and Equations, the the equation is ''work rate'' x ''time'' = ''work done''. Just substitue the information from the problem and voila! , you get your answer! Don't forget to put the stuff, like minutes or hours.

Why can there be extraneous solutions in a logartithmic equation?

Extraneous solutions turn up in a few different p;aces in algebra. One reason they turn up in logarithmic equations is that you can only have a log of a positive number, but when you solve the equation, one of the answers is negative. Did you ever do a word problem about a rectangle and have to solve a quadratic equation? You probably got 2 answers, and had to reject one of them because the length of a rectangle can't be negative. Same idea: the algebra doesn't understand what the problem is about, it just churns out answers!
