Two trains 100 m and 150 m long run in opposite directions at 36 and 54 km/h. Time to cross each other:
A15 s
B12 s
C8 s
D10 s
Answer & Solution
Correct answer: D. 10 s
1. Total length = 100 + 150 = 250 m.
2. Relative speed (opposite directions) = 36 + 54 = 90 km/h = 90·5/18 = 25 m/s.
3. Time = 250 / 25 = 10 s.
