What happens to the velocity of the supersonic flow in the convergent

1.	What happens to the velocity of the supersonic flow in the convergent duct?(a) Decreases(b) Increases(c) Remains the same(d) Changes periodicallyThis question was posed to me in homework.I'd like to ask this question from Area-Velocity Relation topic in section Quasi-One-Dimensional Flow of Aerodynamics
Answer» Right choice is (a) DECREASES The best I can explain: Since the supersonic flows have Mach number greater than 1, the value of M^2-1 is positive. ACCORDING to the area-velocity relation, for a CONVERGENT duct in which dA is NEGATIVE, the velocity decreases.
