Rachel is a stunt driver, and she's escaping from a building that is about to explode! The variable d models Rachel's distance from her exit (In meters) t seconds after the cameras began recording the stunt

What is Rachel's speed?​

The variable d models Rachel's distance from her exit (in meters) t seconds after the cameras began recording the stunt. d = - 38t

Step-by-step explanation:

From given, we have,  The expression that represents the Rachel's distance is given by, d = - 38t + 220                                                                      

where, d represents the distance in meters

            t represents the time in seconds                                                              

We know that, speed = distance by time.  Therefore, we need to differentiate the given equation w.r.t to time to find the speed.

we have,  d/dt (d) = d/dt [- 38t + 220]

| d/dt (d) | = | - 38 + 0 |

s =  d/dt (d) = 38 m/s

Therefore, the speed of Rachel is 38 m/s.
