KUDOS
X=?

(1) interpreting the chart plus the statement: 56 = 2 (y)
INSUFFICIENT bec we don't know anything about x and it's relationship to y.
(2) 69 = 1.5x, SUFFICIENT

SOLUTION

The table above shows the distance, in kilometers, by the most direct route, between any two of the four cities, R, S, T, and U. For example, the distance between City R and City U is 62 kilometers. What is the value of x ?

(1) By the most direct route, the distance between S and T is twice the distance between S and R. We can find the value of $$y$$, which will be $$ST=56=2y$$ --> $$y=28$$. But we have no information about $$x$$. Not sufficient.

(2) By the most direct route, the distance between T and U is 1.5 times the distance between R and T. $$TU=69=1.5x$$ --> $$x=46$$. Sufficient.

(1) By the most direct route, the distance between Sand T is twice the distance between Sand R.
(2) By the most direct route, the distance between T and U is 1.5 times the distance between Rand T.

1) from graph the distance between S and T gives the value of y, hence not sufficient
2) this gives value of x, hence sufficient.

Hence B

R S T U
R 0 28 x 62

S 28 0 56 75

T x 56 0 69

U 62 75 69 0

(1) By the most direct route, the distance between S and T is twice the distance between S and R.
y = 28
This tells us nothing about x.
INSUFFICIENT

(2) By the most direct route, the distance between T and U is 1.5 times the distance between R and T.
tu distance = 69
tu = 1.5(rt)
69 = 1.5(rt)
46=rt
The distance between r and t on the graph = x, therefore, x=46.
SUFFICIENT

for statement 1 - if you know that RS is 28 and ST is 56, why is it incorrect to assume that RT is 28+56?

It would be the distance through S, but there might be a shorter direct route.
