An application of rational functions may involve the number of persons who can do
a task in a certain amount of time. We can handle these applications involving work
in a manner similar to the method we used to solve distance, speed, and time
problems. Work = Rate x Time. Suppose you can finish a report in 2 hours. Your
classmate can finish the same report in 4 hours. How long will it take to finish the
report if both of you work together? We have a saying that “Two heads are better
than one", would you rather work alone or with a team? Why?
