Answer:
Explanation:
The appropriate relation is ...
distance = speed · time
d = 25t
__
The rate of change of Felipe's driving speed* is zero, since his speed is given as constant.
Felipe will drive 150 mile in 6 hours, as found using the equation:
d = 25(6) = 150
_____
* The question posed here asks for rate of change of driving speed. Perhaps, you want rate of change of distance, which is driving speed: 25 miles per hour.
