Rank Relative Velocity

 Shown are six situations where people are walking or running through train cars (the trains are the gray rectangles and the people are the red circles). The velocities of the trains and people are given with respect to the ground in black (train) and red (people), respectively (as a stationary observer on the ground would measure) and given in meters per second. 

Question: Rank the velocity of the people with respect to the train (as a stationary observer on the train would see) from greatest to least. Ties in (  ) please.
