Hint:
A vehicle covers a distance of 390 km while moving at a speed of 130 km/h. The time taken by the vehicle to cover this distance is 3 hours.
The correct answer is: 3
- The speed of a vehicle can be calculated by its speed in relation to the distance it travels.
- Distance = 390 km and speed = 130 km/h.
