A car moves at 45 kilometers per hour. Which option describes if the given value is speed or velocity?

1 velocity, because there is no specific direction
2 speed, because there is no specific direction
3 velocity, because there is a mention of time
4 speed, because there is a mention of time

4. speed, because there is a mention of time

Speed v/s Velocity:Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement. Velocity is speed with a direction. For example: The Dog runs at 9 km/h (kilometers per hour) is a speed. But saying he runs 9 km/h Westwards is a velocity.

Thus, the correct option is 4 since no direction is given so it cannot be velocity.
