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. MCQ with Answer and Explanation

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. 120 km/h
B. 90 km/h
C. 108 km/h
D. 135 km/h
Answer: Option C
Solution (By JKExamLibrary)
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.

Question #2
A train 110 meters long is traveling at 60 km/h. How much time will it take to pass a platform 240 meters long?
A. 27 seconds
B. 21 seconds
C. 24 seconds
D. 18 seconds

Correct Answer: Option B


Explanation:
Total distance = 110 + 240 = 350 meters. Speed = 60 * (5/18) = 50/3 m/s. Time = 350 / (50/3) = 350 * 3 / 50 = 7 * 3 = 21 seconds.
