Question

A train X departs from station A at 11.00 a.m. for
station B, which is 180 km away. Another train Y
departs from station B at 11.00 a.m. for station A.
Train X travels at an average speed of 70 kms/hr
and does not stop anywhere until it arrives at station B.Train Y travels at an average speed of 50km/hr but has to stop for 10 mins at station C which is 60km away from station B enroute to station A. Ignoring the lengths of the train,what is the distance to the nearest km from station A to the point where the trains cross each other?​

Answer 1

Answer:

Time taken by train Y to travel a distance of 60km minutes

Train Y was stationed at point C for 15 minutes, hence total time elapsed to reach point C minutes.

During this period train X covered a distance of or approx km

so distance left between these two train to cover km

as the trains are moving in opposite direction, relative speed km/h

time taken to cover 18km

so distance traveled by train X

Hence train X's distance from A (as rounding was done earlier)

Option A
