Relating linear contexts to graph features?

Kayden is a stunt driver. One time, during a gig where she escaped from a building about to explode(!), she drove at a constant speed to get to the safe zone that was 160 meters away. After 3 seconds of driving, she was 85 meters away from the safe zone.

Let y represent the distance (in meters) from the safe zone after x seconds.

Which of the following could be the graph of the relationship?

    He distance FROM the safe zone is decreasing.

    Obviously y-intercept is POSITIVE.

    That makes C the only feasible option.

    But C shows negative distance from the safe zone.

    Which makes it not feasible under the standard understanding of the term "distance".
