A 300 m long train is moving at a speed of 60 km/h. In what time will it cross a single pole?
Answer & explanation
Correct answer: option 3
A train 300 m long is running with a speed of 60 km/hr.
Time and distance
Speed = 60 km/hr
To convert into m/sec multiply with 5/18
Speed = 60 × (5/18)
Speed = 50/3 m/sec
Time = Distance / speed
Time = 300 × 3/50
Time = 18 second
