Given: t (duration of movement of a given train) = 30 s; V (constant speed) = 54 km / h (in SI V = 15 m / s).
The distance covered by a given train in 30 s is determined by the formula: S = V * t.
Let’s make a calculation: S = 15 * 30 = 450 m.
Answer: In 30 seconds of steady motion, the given train traveled 450 meters.
