Question

 A train travels with a speed of 80kmh-1 from stationX to stationY and then come back with the speed of 100kmh-1 from stationY to stationX. Its average velocity is _   ​

Answer 1

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.....
