Answer
All paths have the same velocity.
Work Step by Step
Since velocity is a vector quantity, direction is taken into account. Set the right as the positive direction.
1. Travels to the right two segments, and the left one segment. This is a net total of one positive segment.
2. Travels one to the the left, and two to the right: net total of one positive segment
3. Travels one to the right: net total is one positive segment
4. Travels 1.5 segments right, 2 to the left, and l.5 to the right: net total one positive segment.
