which best describes a reference frame?\n a distance over which an object moves\n the difference between start and end velocity\n a position from which something is observed\n the average speed of a group of objects

Answer

Brief Explanations:

A reference frame is a position or set of coordinates from which an event or object is observed. It provides a basis for describing motion and position. The other options describe distance, velocity - change, and average speed, which are not related to the concept of a reference frame.

Answer:

a position from which something is observed
