A subway train (10 feet wide and 12 feet tall) is moving at a speed of 50 mph (in the positive x direction) through a long tunnel. The cross-sectional area of the tunnel is three times larger than the cross-sectional area of the train. What is the average fluid velocity (and in what direction is the fluid moving) when the center of the train passes a stationary point in the tunnel?
