    Be a genius, solive this question : ) (Rational Functions)

    If Ms K and Ms E work together they can make a unit test in 1 hour and 1 minute. Working alone Ms V takes 10 minutes less than Ms E to complete the test and 5 minutes longer than Ms K.

    How long do each take on their own to complete a test?

    Thanks a lot, guys.

    Can you please post some attempted work?

    It would be nice to see that you actually tried to solve this problem before asking for help.

    To learn how to set up "work" type exercises, try here.

    Your set-up will involve rational expressions, since the "time" variable will be in the denominators of the "rate" expressions.

    If you get stuck, please reply showing your work and reasoning, after having studied the lesson in the link. Thank you!
