Answer:

4

Explanation:

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.
