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. Answer: B.

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 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
