Answer:

13.5 km.

Step-by-step explanation:

time taken for crossing the pole = 9 sec

time taken for crossing the platform = 29 sec

speed of train 67.5 km/hr

or 67.5*1000/3600

675 MTR / sec.

means train can travel 675 mtr in 1 sec.

so 675*9 sec= 6075 mtr (Train Lenght)

similarly

675*29=19575 (train+plateform)

प्लेटफॉर्म की लंबाई

= 19,575-6,075 mtr

= 13500 mtr

= 13.5 km.
