Reconstruction of the corridor
Calculate how many minutes the travel time will be reduced on a 213 km long railway corridor if the maximum speed increases from 120 km/h to 160 km/h.
Calculate how many minutes the travel time will be shortened if the train must stop at 6 stations, decelerating uniformly at 0.8 m/s² into each station and accelerating at 0.45 m/s² out of each station.
What is the average speed before and after the upgrade if the train stops for 2 minutes at every station?
Assume that the distances between stops are long enough for the train to always reach the speed limit.
Your answer:
