Two trains, 148 m and 152 m long, are running towards each other on parallel lines at 62 km/h and 46km/h, respectively. At what time will they be clear of each other from the moment they meet?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 10 sec.
Total length = 148 m + 152 m = 300 m
Relative speed = 62 + 46 = 108 km/h
⇒ 108 × = 30 m/sec
Time = = 10 sec
