John walks 1.00 km north, then turns right and walks 2.00 km east. His speed is 1.60 m/s during the entire stroll. What is the magnitude of his displacement, from beginning to end? If Jane starts at the same time and place as John, but walks in a straight linnet the endpoint of John's stroll, at what speed should she walk if she wants to arrive at the endpoint just when John does?
