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+220 (I know that the answer is 38 meters per second, but why isint it negative 38 per second, since a negative 38 is in the origanal problem?) thanks
