Answer: a) increases
b) decreases
c) remains the same
Explanation:
a) As time increases, the distance traveled increases because you are traveling from home to work at a rate of 500 ft/min
b) As time increases, the distance remaining decreases because you are getting closer to your goal of 10,000 ft
c) As time increases, the distance from home to work remains the same because the distance from point A (home) to point B (work) hasn't changed - only YOUR distance between them has changed.
