Question

Which of the following correctly describes the relationship between speed and velocity?

A. Speed is the change in velocity over time; velocity is distance plus direction.
B. Speed is the change in distance over time; velocity is speed plus direction.
C. Speed is distance plus direction; velocity is speed plus time.
D. Speed is the change in acceleration; velocity is distance over time.

Answer 1

Option B.

Step-by-step explanation:

As speed is scalar quantity it isn't concerned with direction. But Velocity is a vector quantity that defines change of displacement with time and depends upon direction travelled too.
