39. 00 Cody starts at a point 6.00 km to the east and 4.00 km to the south of a location that represents the origin of a coordinate system for a map. He ends up at a point 10.0 km to the west and 6.00 km to the north of the map origin. (a) What was his average velocity if the trip took him 4.00 h to complete? (b) Cody walks to his destination at a constant rate. His friend Marcus covers the distance with a combination of jogging, walking, running, and resting so that the total trip time is also 4.00 b. How do their average velocities compare? Example 3-3
