A, B, C and P name points.
Answer:
A vector ⇒ answer D
Step-by-step explanation:
* Lets revise some definition to solve the problem
- <em>Speed = distance ÷ time</em>
∵ Distance has no direction
∴ Speed has no direction
∴ Speed is a scalar quantity ⇒ (magnitude only)
- <em>Velocity = displacement ÷ time</em>
∵ 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
You know the solution to the system is equal because it's a number equals to the same number
