A goods train runs at the speed of 72 kmph and crosses a 250 m long platform in 36 seconds. What is the length of the goods train?	Pick one
A) 470 m B) 240 m C) 260 m D) 270 m E) None of these
Explanation:   Speed =[ 72 x (5/18) ]m/sec= 20 m/sec.   Time = 36 sec.   Let the length of the train be x metres.   Then,[ (x+250)/36 ]= 20   =&gt; x + 250 = 720   =&gt; x = 470. 470 mnswer: 470 m
