# Reconstruction of the corridor

Calculate how many minutes will be reduced to travel a 167 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 0.9 m/s2 and from station accelerates 0.35 m/s2?

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

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

t1 =  20.875 min
t2 =  21.3037 min
w1 =  95.4916 km/h
w2 =  119.8177 km/h
