A 270 metres long bullet train running at the speed of 120 kmph crosses another bullet train running in opposite direction at the speed of 80 kmph in 9 seconds. What is the length of the other bullet train ? Choose the correct option:	A) 226	B) 230	C) 430	D) 310	E) 260
230   230   Relative speed = (120 + 80) km/hr   = 200 x 5/18   = 500/9 m/sec   Then, (x+270)/9 = 500/9   --&gt; x + 270 = 500   --&gt; x = 230.
