Answer 2

Answer:

12'o' clock, 150km from A

Step-by-step explanation:

Train A starts at 9am.

Train A @11am:-

speed of train A is 50km/hr.

so @11am train A would have travelled 100km from station A.

therefore @11am the distance between two stations will be 210-100=110km.

Relative speed of two train is 50+60=110km/hr.

so the trains will meet at 110/(50+60) = 1hr

therefore the train will meet at 11am +1hr=12pm.

Distance of train A from station A is.

100+50=150km....... ( since train A travels at a speed of 50km/hr)
