Two trains, each 160 m long, moving in opposite directions, cross other in 8 sec. If one is moving twice as fast the other, then the speed of the faster train is?	Choose the correct choice from the following:
A) 26 km/hr
B) 17 km/hr
C) 60 km/hr
D) 77 km/hr
E) 96 km/hr
Let the speed of the slower train be x m/sec.   Then, speed of the train = 2x m/sec.   Relative speed = ( x + 2x) = 3x m/sec.   (160 + 160)/8 = 3x =&gt; x = 40/3.   So, speed of the faster train = 80/3 = 80/3 * 18/5=
