The man's velocity will be equivalent to that of the walkway to a stationary observer, so it will be 0.4 m/s to the east.

Answer: The velocity of the man according to the stationary observer is 0.4m/s to the east.

Explanation:

A man standing still on the walkaway which is moving with a velocity of 0.4 m/s towards the east. In his frame, his speed will be 0m/s.

But, for a stationary observer, the velocity of the man on the walkaway will be equal to the velocity of the walkaway which is 0.4m/s towards the East.

Had the man, walking on the walkway, his speed would have been added up and the stationary observer must have noticed a different velocity.
