one rainy day, a girl broke up with her bf after being together for 8 yrs. They decided to seperate at the place where they began , at the same time. The boy is due north crying and running at a rate of 5f t /sec and the girl is walking east at a rate of 1f t/sec thinking if she made the right decision. How fast are they seperating from each other 5 seconds after they started moving to thier new lives without each other.
