Two trains 110 meters and 90 meters long are running in opposite directions at speeds of 36 km/h and 54 km/h respectively. In what time will they pass each other completely?
A. 12 seconds
B. 10 seconds
C. 8 seconds
D. 6 seconds
Answer: Option C
Solution (By JKSSB Mock Tests)
Total distance = 110 + 90 = 200 meters. Relative speed in opposite directions = 36 + 54 = 90 km/h = 90 * (5/18) = 25 m/s. Time taken = 200 / 25 = 8 seconds.
