First train 108 m long moving at a speed of 50 km/hr crosses a second train 112 m long coming from opposite direction in 6 seconds. Find the speed of the second train ??  Options.
A) 82 km/hr	B) 80 km/hr	C) 90 km/hr	D) 60 km/hr	E) 62 km/hr
speed of the second train consider as x   relative speed = (x+50)*5/18 m/sec   (250+5x/18) m/sec   distance = (108 + 112)=

<output>220</output>
220 m==&gt; 220/(250+5x/18) = 6   250 + 5x = 660   =&gt;x = 82 km/hr   82 km/hrNSWER 82 km/hr
