Answer: Only statements 2 and 3 are correct.
- 1 is incorrect: velocity is based on displacement (a vector) not on total distance (a scalar).
- 2 is correct: velocity includes direction (it’s a vector quantity).
- 3 is correct: you can talk about average velocity (Δx/Δt) or instantaneous velocity (dx/dt).
Example: If you walk 3 m east then 3 m west in 6 s, total distance = 6 m so average speed = 6/6 = 1 m/s, but displacement = 0 so average velocity = 0 m/s.
