Step-by-step explanation:
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 =
60
40(x+11)
km
Then train cover distance in x+5 minuets at speed 50 km\hr =
60
50(x+5)
km
Both are same then
60
40(x+11)
=
60
50(x+5)
∴40x+440=50x+250
∴−10x=−190
∴x=19 minutes
