From the question stem, we can deduce that the relative speed of the two trains when they passed each other was 250/2 = 125 miles per hour. This indicates that the sum of P's average speed and Q's average speed at the time they passed was 125 miles per hour.
However, this cannot be applied to the second statement because it provides Q's average speed for the entire journey, not specifically at the time they passed each other. Without knowing Q's speed at that moment, we cannot determine the individual speeds of P or Q at the time of passing, nor can we calculate the distances they had covered.

Why Option (D) Makes More Sense than Option (A)
Upon reviewing the problem, here’s the reasoning that leads us to conclude that the correct option should be (D) rather than (A):
Upon reviewing the problem, here’s the reasoning that leads us to conclude that the correct option should be (D) rather than (A):
- Total Distance and Meeting Time
The total distance between the trains is given as 250 miles, and they meet in 2 hours. Therefore, we know that the combined speed of the two trains must be:
250/2 = 125mph - Individual Speeds of Each Train
We are told that Train Q travels at 55 mph. Since the sum of both trains’ speeds is 125 mph,
Train P's speed must be:125 mph−55 mph=70 mph - Distance Traveled by Each Train
In the 2 hours before they meet,
Train Q covers:55 mph×2 hours=110 miles
Meanwhile, Train P covers:70 mph×2 hours=140 miles

Bunuel,
Doesn't then "At the time" for statement 1

then mean that speed when passing so earlier speed of A before crossing each other will be different and hence NS ?
