The ants of the North Creek Ant Colony traverse a straight trail between their colony and a nearby picnic table. One ant, returning after quenching its thirst with a portion of a tasty beverage dripping from the table, is first observed along the trail 4.5 m from the colony. Then, after traveling a total of 1.8 m while staggering back and forth along the trail, the ant falls unconscious 1.9 m from the colony exactly 43 s later. Defining the entrance of the colony as the origin and the positive direction toward the picnic table, determine the ant's average velocity avg during this time interval.
