# Reconstruction of the corridor

Calculate how many minutes will be reduced to travel 187 km long railway corridor, where the maximum speed increases from 120 km/h to 160 km/h.

Calculate how many minutes will shorten travel time, if we consider that the train must stop at 6 stations, each station with the equally slow 0.8 m/s

What is the average speed before and after reconstruction, if train stay for 2 minutes in every station?

Consider the intermediate stops are so long that the train will always reach speed limit.

Calculate how many minutes will shorten travel time, if we consider that the train must stop at 6 stations, each station with the equally slow 0.8 m/s

^{2}and from station accelerates 0.5 m/s^{2}?What is the average speed before and after reconstruction, if train stay for 2 minutes in every station?

Consider the intermediate stops are so long that the train will always reach speed limit.
