A train passes a pedestrian standing on a platform in 6 seconds and passes the platform itself, which is 150 meters long, in 11 seconds. Find the speed of the train in km/h.
A. 90 km/h
B. 135 km/h
C. 120 km/h
D. 108 km/h
Answer: Option D
Solution (By JKSSB Mock Tests)
Time taken to cross the platform alone = 11 - 6 = 5 seconds. Speed of train = 150 / 5 = 30 m/s. In km/h = 30 * (18/5) = 108 km/h.
