Solving a Work Application: Printing Presses
Apply the problem-solving strategy for work applications to find how long it takes two printing presses to complete a job together. If Press #1 takes hours alone and Press #2 takes hours alone, let be the hours needed together. In hour, Press #1 completes of the job, Press #2 completes of the job, and together they complete of the job. The rational equation is: Multiply both sides by the LCD, : Distribute and simplify: When both presses are running together, it takes hours to complete the job.
