Show answer & explanation
Correct answer: C
Solution: 3
Distance covered by train in crossing the platform of 100 meters is (100 + 50) = 150 meters.
Time taken to cross the platform = 10 seconds.
Speed = Distance/Time
⇒ Speed of train = 150/10 = 15 m/s
∴ Speed of train = 15 m/s
= 15 × (18/5) km/hr
= 54 km/hr
