Answer:
Yes.
Step-by-step explanation:
The relation would be 3 = k*9 as there is a direct proportional relationship.
So k = 3/9 = 1/3 and we can write the relation as d = 1/3 t where d=distance and t = time.
So if we double the time t we have:-
d = 1/3 * 18
= 6 kilometers.
So the distance is doubled.
