Displacement over time is velocity - distance over time is speed.
The reason is that:
Displacement is a vector quantity (has a direction as well as a magnitude), whereas speed is a scalar quantity (has no direction, only magnitude).

Average speed (83 mph) is a measure of the change in location relative to some fixed point (or displacement) divided by the amount of time taken for that change.The change in location and the passage of time are independent of the location of the observer and hence the result.Average speed (83 mph) is a measure of the change in location relative to some fixed point (or displacement) divided by the amount of time taken for that change.The change in location and the passage of time are independent of the location of the observer and hence the result.Average speed (83 mph) is a measure of the change in location relative to some fixed point (or displacement) divided by the amount of time taken for that change.The change in location and the passage of time are independent of the location of the observer and hence the result.Average speed (83 mph) is a measure of the change in location relative to some fixed point (or displacement) divided by the amount of time taken for that change.The change in location and the passage of time are independent of the location of the observer and hence the result.
displacement+time divided by distance
Displacement divided by time is VELOCITY. Definition of velocity is rate of change of displacement with respect to time. Suppose a object gets displaced by 5m in 2 seconds, its velocity will be5/2=2.5 m/s(m/s is its unit).It means that object will go 2.5m in 1 second. Let us take oone more example. Say a object has moved by 6m in 12 seconds, Its velocity will be:6/12=0.5m/s Means it will cover a distance of 0.5m in one second.
(Angular displacement divided by 360 degrees or pi radians)/(Time measured in minutes)
It is the rate of change - with respect to time - of the angular displacement.
