Aturtle ambles leisurely, as turtles tend to do, when it moves from a location with position vector 1,=1.91 m and 1,=−2.73 m in a lettuce garden to another location, with position vector 2,=3.65 m and 2,=−4.79 m, where the lettuce appears to be tastier (but really is not; this turtle cannot see very well). the excursion takes 304 s to complete. what are the components and the magnitude of the turtle's average velocity in meters per second?
