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
