The train travels a distance of 330 km at a speed of 60 km / h. What is the average speed

The train travels a distance of 330 km at a speed of 60 km / h. What is the average speed of the train along the entire route if 30 minutes are spent on all stops at intermediate stations?

Task data: S (distance traveled) = 330 km; V (travel speed) = 60 km / h; t1 (time spent at stops at intermediate stations) = 30 min (0.5 h).

1) Let’s define the “net” time of the train movement: t = S / V = 330/60 = 5.5 hours.

2) Let’s calculate the total travel time: ttotal = t + t1 = 5.5 + 0.5 = 6 hours.

3) Determine the average speed: Vav = S / ttotal = 330/6 = 55 km / h.

Answer: The average speed is 55 km / h along the entire route.
