Initial data: t (duration of movement of the considered passenger train) = 30 min = 1800 s; S (distance traveled) = 30 km = 30 * 103 m.
The constant speed of the passenger train under consideration is calculated by the formula: V = S / t.
Calculation: V = 30 * 103/1800 = 16.67 m / s (60 km / h).
Answer: The constant speed of the passenger train in question is 60 km / h.
