The velocity of the train is 30 km/h west.

Definition of velocity

Velocity can be determined by dividing the total displacement travelled by the total time travelled. The direction of travel is also added.

Calculation of velocity

  • Total displacement = 80 km + 40 km = 120 km
  • Total time = 1 hour + 1 hour + 2 hours = 4 hours
  • Direction = west

Velocity = 120 km / 4 hours = 30 km/h west.
