The table below shows the time schedule of Saraighat Express, Train n...
Here, Time = Arrival time in new station - Dept. time from previous station
Distance between two stations = Distance of 2nd station from Howrah - Distance of 1st station from Howrah
Avg. Speed = Distance/Time
Total time taken to reach NJP = (74+47+59+104+45+110+123+ 80) =642 mins (we are excluding the stoppage time in each station).
Total Distance between Howrah & NJP=560 Km
So the avg. speed for the 1st half of the journey=560/642 km/min=52.33 Km/hr
The time taken to reach GHY from NJP= (135+18+108+165+21-80) (as train reaches GHY at the scheduled time thus it took 80 mins less to reach GHY from NJP) = 367 mins
Total distance between NJP and GHY=459 Km
So the avg. speed for the 2nd half of the journey=459/367 Km/min =75 Km/hr
So the difference in speed = 75 - 52.33 =22.67.
