 
 <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). <hau> A cikin 10s jirgin ya haye sandar kuma a cikin 30 sec jirgin ya haye wani jirgin kasa mai tsayawa A cikin dakika 20 jirgin ya yi tafiyar mita 600 Saurin = 600/20 = 30 m / s = 30 (3600/1000) = 30 * 18/5 = 108 kmph Don haka, amsar ita ce (C).
