skelet666 [1.2K]

Answer:

38 m/s

Step-by-step explanation:

We are given that

D represent Rachel's remaining distance( in meters ) as  a function of time is given by

D=-38t+220

We have to find the Rachel's speed.

We know that

Velocity=\frac{ds}{dt}

Substitute the values then we get

v=\frac{d(-38t+220)}{dt}=-38 m/s

Speed =\mid v\mid

Speed =\mid -38\mid =38m/s

Hence, the Rachel's speed is given by =38 m/s
