An electronic computer can be used to generate a large stock portfolio analysis in 6 minutes. With the help of a new computer, the analysis can be run in 2 minutes. How long would it take the new computer to run the analysis alone?
Let x equal the number of minutes the new computer takes to generate a large stock portfolio by itself. In one minute, the new computer can do 1/x of the task and the first computer can do 1/6 of the task. As an equation, this information looks like 1/x+1/6=1/2, where 1/2 is the analysis that both computers can generate togther in one minute. Multiply both sides of the equation by the least common denominator(LCD), 6x, to get an equation of 6+x=3x. Combine like terms, 6=2x. Thus, x=3 minutes is the time it takes for the new computer to run the analysis alone. I read this logic from the book, "Express Review Guide-Algebra".
