Answer:
Hello, Good Morning
The answer is given below.....
Explanation:
As you've not mentioned about the time... I've solved the alternate method....
The train travels from Station X to Station Y at a speed of 80 km/h.
The train travels back to Station X at a speed of 100 km/h.
Finding the Average Velocity, we get the Average as 90 km/h.
Because, The Formula of the Average Velocity is =
If the acceleration is uniform, Initial + Final Velocities / 2
Initial Velocity (u) = 80 km/h
Final Velocity (v) = 100 km/h
Therefore, 80 + 100 / 2 gives,
180 / 2 = 90 km/h.
HOPE THIS HELPS...
Have a Great Time.....
