Question

• A. In an accelerated motion
• B. In a decelerated motion
• C. in a uniform motion with zero acceleration
• D. Never

Answer 1

in a uniform motion with zero acceleration

Instantaneous speed means speed of a body measured at any instant during the motion.
At any point of time, instantaneous speed will be equal to the average speed only if the body moves with a uniform speed throughout.
