The metro train moves along the circular line, the length of which is 24 km. The travel time of the route of the line is 30 minutes. Find the value of the average speed of the train during this time.
Task data: L (length of the circular line) = 24 km; Δt (travel time of the line) = 30 min (0.5 h).
The average speed of movement of the train in question is determined by the formula: Vav. = ΔS / Δt, where ΔS is the movement of the train in 30 minutes (for the circular line ΔS = 0 m, the train passed exactly one circular line).
Calculation: Vav. = 0 / 0.5 = 0 m / s.
Answer: The average speed of the train is 0 m / s.
