 <translate> In 10s the train crosses the pole and in 30 sec the train crosses one more stationary train
In 20 sec the train travels a distance of 600 mtrs
Speed = 600/20 = 30 m/s = 30 (3600/1000) = 30 * 18/5 = 108 kmph So, the answer is (C). <yor> Ni 10s ọkọ oju irin naa kọja ọwọn ati ni 30 sec ọkọ oju irin naa kọja ọkọ oju irin iduro kan diẹ sii Ní ìṣẹ́jú ogún, ọkọ̀ ojú irin náà máa rin ìrìn àjò ọgọ́rùn-ún méje. Iyara = 600/20 = 30 m/s = 30 (3600/1000) = 30 * 18/5 = 108 kmph Nítorí náà, ìdáhùn náà ni (C).
