The well-fed ants of the Fourth North Creek Ant Colony maintain and adhere to a straight trail along the ground between the nearby picnic table and the hole leading to their underground nest. In the colony's folklore, this trail has been known
since ancient times as the x-axis. One member of the colony, returning to the nest after quenching its thirst with a serious
portion of a tasty beverage dripping from the picnic table, is observed first at position x; = 9,69 m on the trail. Then it is
seen staggering back and forth along the trail, eventually stopping for a nap at position xi = 8,21 m exactly 96.3 s later,
Find the ant's average velocity during this time interval.
