Question

A train is traveling at a constant speed and has traveled 67.5 miles in the last 1(1)/(2) hours. Which equation shows the proportional relationship between the distance, d, and the time, t, that the train has traveled?

a)d=45t
b)d=50t
c)d=67.5t
d)d=69t

Answer 1

a)

Explanation:

By definition; for constant speed,

S = ∆d/t

= 67.5/1.5

= 45

Therefore, the relationship between d and t is giving as; d = 45t
