Answer

Path 4 has the greatest average speed. Paths 1 and 2 are tied for next greatest speeds. And Path 3 has the least speed.

Work Step by Step

Speed is a scalar quantity, so direction is not measured. All the paths travel over the same time period, so speed is measured solely by how much distance it travels. Path 4 travels a total of 4 segments. Paths 2 and 1 travel three segments. Path 3 travels one segment.
