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? Choices: A) 230 m B) 240 m C) 260 m D) 270 m E) 290 m
72 Kmph=72*5/18= 
<gadget id="calculator">72*5/18</gadget>
<output>20</output>
20m/s   The train has to cover its length and the length of the platform   so the total distance=250+l   250+l=20*26   250+l=520   l=520-250= 
<gadget id="calculator">520-250</gadget>
<output>270</output>
270m   length of the train=270m   ANSWER:270 m
<result>D</result>
