Answers
A) 12  B) 36  C) 28  D) 20  E) 24
Explanation:   Distance covered = 120+120=

<output>240</output>
240 m   Time= 36 s   Let the speed of each train = v. Then relative speed = v+v = 2v   2v = distance/time = 240/36 = 6.667 m/s   Speed of each train = v = 6.667/2 = 3.33 m/s   = 3.33×36/10 km/hr = 12 km/hr   12nswer: Option 12
