Answer: 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
