The table above shows the morning schedule for train X. If Juan took train X on Monday morning, did he arrive at station T on schedule?

1) Juan arrived at station T on Monday morning 1 hour and 2 minutes after he left station S.
2) Juan arrived at his office at 8:30 (East) on Monday morning, which was 20 minutes after he arrived at station T.

OA B

Let's take each statement one by one.

1) Juan arrived at station T on Monday morning 1 hour and 2 minutes after he left station S.

Case 1: If John started from station S at 7:08, he arrived at station T at 8:10, scheduled time. The answer is yes.
Case 2: If John started late from station S at 7:08, he would not have arrived at station T at 8:10, scheduled time. The answer is no.

No unique answer. Insufficient.

2) Juan arrived at his office at 8:30 (East) on Monday morning, which was 20 minutes after he arrived at station T.

=> John reached station T at 8:30 - 20 minutes = 8:10, scheduled time. The answer is yes. Sufficient.

The correct answer: B

Hope this helps!
