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 6 hours alone and Press #2 takes 12 hours alone, let be the hours needed together. In 1 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 least common denominator (LCD), , to get . Distribute and simplify to obtain , which becomes , yielding . When both presses are running together, it takes 4 hours to complete the job.
