Speed of a goods train is 72 km/hr. This train crosses a 250 meter platform in 26 seconds. Then find the length of goods train.	Choose the correct choice from the following:
A) 250 meters	B) 260 meters	C) 270 meters	D) 280 meters	E) 290 meters
Explanation:   First convert speed from km/hr to m/sec   So, Speed = 72*(5/18)= 
<gadget id="calculator">72*(5/18)</gadget>
<output>20</output>
20 m/sec   Time= 26 seconds   Let the length of the train be x meters.   We know, Distance = Speed*Time.   [you can remember this formula as remembering DUST = D*ST... Distance=Speed*Time]   x+250 = 20*26   =&gt; x = 270 meters   So length of the goods train is 270 meter   Option 270 meters
<result>C</result>
Speed of a goods train is 72 km/hr. This train crosses a 250 meter platform in 26 seconds. Then find the length of goods train.
