Rachel is a stunt driver, and she's escaping from a building that is about to explode! ddd represents rachel's remaining distance (in meters) as a function of time ttt (in seconds). d=-38t+220d=−38t+220d, equals, minus, 38, t, plus, 220 what is rachel's speed?

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

We have to find the Rachel's speed.

We know that

Substitute the values then we get

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

true? is that what you're asking or do you mean something else?
