The following GMAT data sufficiency question tests your understanding of applying distance, rate, and time relationships to problems tested on the GMAT.

**Question 45**:

Trains $A$ and $B$ left stations $R$ and $S$ simultaneously on two separate parallel rail tracks that are $350$ miles long. The trains passed each other at point $X$ after traveling for a certain amount of time. How many miles of the rail tracks had train $A$ traveled when the two trains passed each other?

- (1) Up to point $X$, the average speed of train $B$ was $25\%$ less than the average speed of train $B$.
- (2) Up to point $X$, the average speed of train $B$ was $60$ mph and it took two and a half hours for train $B$ to arrive at point $X$.

- Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
