Answer:

Hence , the distance to be covered by the train is 20 km .

Answer:

Let the correct time for the train to complete the journey is x minuets

Then train cover distance in x+11 minuets at speed 40 km\hr = 40(x+11)/60 km

Then train cover distance in x+5 minuets at speed 50 km\hr = 50(x+5)/60 km

Both are same then

40(x+11)/60= 50(x+5)/60

∴40x+440=50x+250

∴−10x=−190

∴x=19 minutes
