That's called the speed.
The distance an object travels per unit of time is called its speed, or velocity if you are also considering its direction of travel. This could be measured in meters per second, kilometers per hour, inches per year or any other unit of measure that divides distance by time.
That's the object's speed.

Speed
No, the distance an object travels in unit time is called speed. The distance travelled per unit time in a specified direction is called velocity. The rate of change of velocity is called acceleration.
That's the object's "speed". (NOT velocity.)
slope
Light years: the distance that light travels in a year.
