Question

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 160160160 meters away. After 333 seconds of driving, she was 858585 meters away from the safe zone.
Let D(t)D(t)D, left parenthesis, t, right parenthesis denote the distance to the safe zone DDD (measured in meters) as a function of time ttt (measured in seconds).
Write the function's formula.

75 meters in 3 seconds.

That's 25 meters per second.

 

D(t) = 160 - 25t
