Two trains 100 meters and 120 meters long are running in the same direction with speeds of 100 km/hr, 82 km/hr. In how much time will the first train cross the second
Choose the correct answer
A) 37 sec
B) 35 sec
C) 48 sec
D) 44 sec
E) 36 sec
Explanation:   Relative speed of the trains = (100 - 82) km/hr = 18 km/hr   = (18Ã— 5/18) m/sec = 5 m/sec.   Time taken by the trains to cross each other   = Time taken to cover (100 + 120) m at 5 m /sec = (220/5)=
