it's destination late by 11 minutes. But if it
runs at so kmph it is late by 5 minutes
aly. Find the distance to be covered

Answer 1

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 = 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

6o

40(x+11)

= 60

50(x+5)

∴40x+440=50x+250

∴−10x=−190

∴x=19 minutes
