correct answer is: 25/4 secs
Explanation: The two trains are moving towards each other, so their relative speed is the sum of their individual speeds: 18 m/s + 22 m/s = 40 m/s. The total distance they need to cover to cross each other is the sum of their lengths: 125 m + 125 m = 250 m. Using the formula time = distance / speed, the time taken for the trains to cross each other is 250 m / 40 m/s = 6.25 seconds, which is equivalent to 25/4 seconds.

• OPTION a: Correct, as calculated above.
• OPTION b: Incorrect, 5 seconds is too short.
• OPTION c: Incorrect, 48 seconds is too long.
• OPTION d: Incorrect, 7 seconds is also too long.
