A subway train travels between stations a distance of 6 km in 4 minutes. Determine the speed of the train.

Task data: S (distance traveled between stations) = 6 km (in SI system S = 6 * 10 ^ 3 m); t (time required) = 4 minutes (in SI t = 240 s).

To determine the speed of a given subway train, use the formula: V = S / t.

Calculation: V = 6 * 10 ^ 3/240 = 25 m / s.

Answer: The given subway train was moving at a speed of 25 m / s.
