38 meter per second

Step-by-step explanation:

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

where -38 is the rate of change of function .

Since speed is the rate of change of position with respect to time , thus

Speed =-38 meter per second which shows decrease in distance with respect to time.

At t=0 second, d=220 meters

At t=1 second , meters

Distance traveled in 1 second = 220-182=38

Now, Rachel's speed=

Rachel's speed==38 meter per second
