Question

A train travels at 75 miles per hour. What equation that compares the time (t) with the distance (d)?

d = 75t
t = 75d
t = d + 75
d = t + 75

Answer 1

The domain is time (t) and the range is distance (d).

Answer 2

The answer is d=75(t).

d is dependant on 75(t).… meaning: a train covers a certain amount of ground (distance =d) depending on the hour.
