After pausing for 15 minutes, she begins running at a 5:50 pace (minutes/mile) NW for 1 mile. Finally, she finishes her journey at Point-B by walking 200m West in 120s. Julie begins her walk from Point-A at the same instant Jennifer begins. Julie's end location will also be Point-B. How far will Julie need to walk, and at what speed, so that she and Jennifer arrive at Point-B at the same time? Hint #1: Speed = Hint #2: AutoCAD (Distance / time)
