A train 110 m long travels at 60 kmph. How long does it take to pass a...
Given data:
Length of the train (l) = 110 m
Speed of the train (s) = 60 kmph
To find:
Time taken by the train to pass a telegraph post by the side of the track.
Formula used:
Time taken = Distance / Speed
Calculation:
1 kmph = 5/18 m/s (meters per second)
Speed of the train in m/s = 60 × 5/18 = 16.67 m/s
Distance covered by the train to pass the telegraph post = length of the train = 110 m
Time taken by the train to pass the telegraph post = distance/speed = 110/16.67 = 6.6 seconds
Therefore, the time taken by the train to pass a telegraph post by the side of the track is 6.6 seconds.
Answer: Option (c) 6.6 seconds.
