A goods train runs at the speed of 72 kmph and crosses a 250 m long platform in 26 seconds. What is the length of the goods train?
Choose the correct choice from the following answers: A) 230 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 = 26 sec.   Let the length of the train be x metres.   Then,[ (x+250)/26 ]= 20   =&gt; x + 250 = 520   =&gt; x = 270. Answer: 270 m
