1.	10 If a train runs at 40 kmph it reachesit's destination late by 11 minutes. But if itruns at so kmph it is late by 5 minutesaly. Find the distance to be coveredby the train.
Answer» 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 i THINK so this answer may be HELPFUL for you!!!

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

40(x+11)

= 60

50(x+5)

∴40x+440=50x+250

∴−10x=−190

∴x=19 minutes

i THINK so this answer may be HELPFUL for you!!!
