This one is from the OG.
A certain expressway has exits J, K, L, and M, in that order. What is the road distance from exit K to exit L?
1) The road distance from J to L is 21 kilometers
2) The road distance from K to M is 26 kilometers
E
I don't understand why the answer isn't C.

Let’s say JK = x, KL = y and LM = z.
To answer the question we need to find y.
Using 1: x + y = 21 cant calculate y.
Using 2: y + z = 26 cant calculate y.
Using both the statements together we still cant compute as we have three variables and only two equations.
