Answer
Distance is the total length of the path taken by an object in motion, measured in meters (m). It is also a scalar quantity that represents the magnitude of displacement without regard to direction.

Answer
Speed is the rate at which an object covers distance, calculated as distance traveled divided by the time taken. It is measured in meters per second (m/s) and is a scalar quantity, indicating how fast an object is moving regardless of direction.
