How is acceleration calculated?
-acceleration equals the change in velocity divided by time
-acceleration equals distance divided by time
-acceleration equals speed multiplied by time
-acceleration equals velocity

Acceleration equals the change in velocity divided by time.

That's the "time rate of change" of velocity.
