Expert Answer:

The average speed of the train is 120/80 = 3/2 km/minutes = 1.5 km/min
Distance travelled in 1 hour = Distance travelled in 60 minutes = 1.5 x 60 = 90 km
As the train passes station Z in 1 hour after leaving station X, so the distance between X and Z = 90 km
Now, DIstance between Y and Z = (Distance between X and Y) - (Distance between X and Z) = 120 - 90 = 30km
