You walk for 6.44 km at a constant speed of 2.54 m/s due west, turn around, and then walk with an average speed of 0.440 m/s due east. From your starting point to your destination, the magnitude of your overall average velocity (!) is 1.25 m/s (due west). During the trip, how far east did you walk (i.e. how many meters due east have you been walking after making the turn)?
