An earthquake wave travels through 55 km of rock in 25 seconds. Which equation represents the relationship between t, the number of seconds, and d, the total distance the wave travels?
A. d = 80t
B. d = 2.2t
C. d = 511t
D. d = 147t

Therefore, the relationship will be of the form, y = mx + b, or in this case, d = (max distance / max time)t + 0.
