Question 1008610
Too strange.  If the description is for travel and destination, why should the distance decrease as time progresses?  Negative slope, meaning rate in some opposite direction.  As a SPEED, this makes no sense.


Ignoring that, look at either the graph or the function definition.  Linear function;  speed is  25 MILES per HOUR.  According to the graph and the function in symbols, NEGATIVE 25 miles per hour.
