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 DDD represent the distance (in meters) from the safe zone after ttt seconds.

Complete the equation for the relationship between the distance and number of seconds.
