Train length=315m

Train speed=54kmph=>54*(5/18)=>15m/s

Distance of pole is negligible so the total length is just the length of the train.

Therefore, Time=Distance/Speed

=315/15= 21 seconds .

Answer:

21 s

Explanation:

Speed = 54km/h = (54 × 5/18) m/s = 15 m/s

Length of the train = 315 m

Time = Distance/ speed = 315/15 = 21 s
