Which describes a vector quantity?

Question

Which describes a vector quantity??  
A. 5 miles per hour due southwest  
B. 5 miles per hour  
C. 5 miles  
D. None of the above

Accepted Answer

Correct Answer: (A)5 miles per hour due southwest. 
Rationale: A vector quantity is described by “5 miles per hour due southwest.”A vector quantity must include both a magnitude (how much) and a direction (which way). Velocity is a classic example of a vector because it specifies not only speed but also the direction of motion.A) 5 miles per hour due southwestThis description includes a numerical value (5 miles per hour) and a direction (due southwest). Because it contains both magnitude and direction, it qualifies as a vector quantity.B) 5 miles per hourThis describes speed only, without any direction. Speed is a scalar quantity, not a vector.C) 5 milesThis represents distance, which has magnitude but no direction. Distance is also a scalar quantity.D) None of the aboveSince option A correctly describes a vector quantity, this choice does not apply.ConclusionVector quantities require both magnitude and direction. Among the options given, only “5 miles per hour due southwest” satisfies this requirement.
