A train 100 meters long running at 90 km/h crosses another train 150 meters long running at 54 km/h in the same direction. How much time do they take to cross each other?
A. 35 seconds
B. 20 seconds
C. 30 seconds
D. 25 seconds
Answer: Option D
Solution (By JKSSB Mock Tests)
Total distance = 100 + 150 = 250 meters. Relative speed in same direction = 90 - 54 = 36 km/h = 36 * (5/18) = 10 m/s. Time taken = 250 / 10 = 25 seconds.
