There is only one rifle described in the question and it travels 0 m. nice try.
The whole question is shown below:
An observer stands 26 m behind a marksman practicing at a rifle range. The marksman fires the rifle horizontally, the speed of the bullets is 790 m/s, and the air temperature is 20°C. How far does each bullet travel before the observer hears the report of the rifle? Assume that the bullets encounter no obstacles during this interval, and ignore both air resistance and the vertical component of the bullets' motion.

When is a body said to be in motion in relation to an observer?
when position of the body with respect to an observer change with time then the body are said to be in motion.
How the apparent motion of a object depend on the observer motion?
The apparent motion of an object can vary depending on the motion of the observer. This is due to the concept of relative motion, where the perception of an object's movement is influenced by the observer's own motion. For example, if the observer is moving towards an object, the object may appear to move faster than if the observer is stationary.
What part of speech is observer?

Is a blue flame the same temperature as a blue star?
No. The blue colour shown by a flame is an indication of the temperature but the blue colour of a star indicates it's direction of movement, in this case towards the observer.
