A train speeds past a pole in 15 seconds and a plaƞorm 100 meter long in 25 seconds. What is length
of the train ?	Choices:  A) 140 meter  B) 145 meter  C) 150 meter  D) 155 meter  E) None of these
Explanation:   Let the length of the train is x meter and Speed of the train is y meter/second   Then x/y = 15 [because distance/speed = Ɵme]   =&gt; y = 15/x   =&gt;x+10025=x15x=150 meters   So length of the train is 150 meters   Answer: 150 meter
