Since the walker turns around and goes backmwards, subtract the second distance from the first. Then divide by the time for the AVERAGE velocity. They asked for average speed, which is something else. It would depend upon how much time was spend travelling at each speed.
They also fail to distinguish between average and instantaneous speed. The question was poorly phrased.
