rational expression

 Rational expressions are often used in combining rates of work. For this discussion, you are asked to pick a task that is done around your house or in your job and complete the following:

  • Identify the task.
  • Pick at least three people that you know, who also know how to do the task.
    • Ask the person to perform the task.
    • Identify each person and record the time it takes for the person to complete the task.
  • Perform a rate of work calculation to determine how long it would take all people assessed to perform the task together. Share your calculations.
  • Does the value you calculated make sense? Why?
  • Would it be reasonable to have the task performed in this manner? Why or why not?
