Question

Answer 1

the distance moved per unit of time is speed.
In kinematics, the speed of an object is the magnitude of its velocity(the rate of change of its position); it is thus a scalar quantity. The average speed of an object in an interval of time is the distance travelled by the object divided by the duration of the interval; the instantaneous speed is the limit of the average speed as the duration of the time interval approaches zero.
