Train A
200miles/40miles per hour =5 hours

Train B
250miles/60miles per hour = 4.16hours

Train A will arrive at 8 AM plus 5 hours or 1PM
Train B will arrive at 12PM plus 4.16 hours or 4:10 PM

Train A will arrive first. 3 hours and 10 minutes ahead of train B.
Direction makes no difference

Train A:

200/4 = 5

8AM + 5 = 1PM

Train B:

250/60 = 4.16...

12PM + 4.16... = 4.16PM

So Train A will arrive there first!
