Two trains of length 210 m and 120 m are 160 m apart. They start moving towards each other on parallel tracks, at speeds 74 kmph and 92 kmph. After how much time will the trains meet? Choose the correct choice from the following choices
A) 35/10  B) 31/10  C) 31/10  D) 36/10  E) 37/10
They are moving in opposite directions, relative speed is equal to the sum of their speeds.   Relative speed = (74 + 92)*5/18 = 46.1 mps.   The time required = d/s = 160/46.1= 35/10 sec.   35/10nswer:35/10
