Explanation:
The velocity of the train will be 75km/hr due east.
- Velocity is given as the rate of change of displacement with time.
Velocity = 
- Velocity is a vector quantity that has both magnitude and directions.
- It is different from speed because it has the directional attribute.
- From the given data, we know that the train is moving at 75km per hour. This is the speed of the train.
- If we incorporate the direction then we have its velocity.
