Message:  It takes Mary 7 hours to clean the house. It takes her sister Jane 5 hours to clean the house. When Mary, Jane, and their youngest sister Sarah all clean the house together, it takes them 2.5 hours. How long would it take Sarah to clean the house by herself?


Hint: Sarah's pretty young, so it would take her a pretty long time...but you can solve exactly how long it would take her!
