Answer:
Found this on google, "Speed, being a scalar quantity, is the rate at which an object covers distance. The average speed is the distance (a scalar quantity) per time ratio. ... On the other hand, velocity is a vector quantity; it is direction-aware. Velocity is the rate at which the position changes."
The answer to your question is D)D Velocity is the change in speed over time, while speed is the change in distance over. Sorry if i am incorrect.
Hope this helps, have a nice day and stay safe!
Happy Halloween, have a good weekend! :) :D
