A 270-metre-long train running at the speed of 120 kmph crosses another train running in opposite direction at the speed of 80 kmph in 9 secs. What is the length of the other train?	Choose the most appropriate option:
A) 240 metres
B) 320 metres
C) 260 metres

200 × 5⁄18 m/sec   t= 230 metresistance/Speed=(270+x)×9/500   or 270 + x = 9×500/9x = 500 – 270 = 230 m   Answer 230 metres
