The relationship between rate of speed (r), distance traveled (d), and time traveled (t) is given by the following equation.
r=d/t
If rate remains constant, which of the following must be true?
a. If distance increases, time traveled must also increase.
b. If distance decreases, time traveled must also decrease.
c. If distance increases, time traveled may increase or decrease depending on rate of speed.
d. If distance decreases, time traveled may increase or decrease depending on rate of speed.
