Answer:
A vector ⇒ answer D
Step-by-step explanation:
* Lets revise some definition to solve the problem
- Speed = distance ÷ time
∵ Distance has no direction
∴ Speed has no direction
∴ Speed is a scalar quantity ⇒ (magnitude only)
- Velocity = displacement ÷ time
∵ Displacement has direction
∴ Velocity has direction
∴ Velocity has magnitude and direction
∵ Any vector has magnitude and direction
∴ Velocity is a vector quantity
∵ Velocity describes both speed (magnitude) and direction
∴ Velocity is a vector
