Rachel is a stunt driver. one time, during a gig where she escaped from a building about to she drove to get to the safe zone at 24 meters per second. after 4 seconds of driving, she was 70 meters away from the safe zone

Step-by-step explanation:

Let

D(t) = the distance to the safe zone (measured in meters)

t = time (measured in seconds)

Given:

Rachel's rate = 24 meters per second

At seconds meters

Find: D(t)

Rachel's rate is the slope of the function D(t). Since the distance is decreasing when the time is increasing, the slope must be negative.

Hence, the function expression is

To find b, substitute and  

So,
