Two trains, 280 metres and 260 metres long, respectively, are running towards each other on parallel lines, one at the speed of 58 km/hr and another at the speed of 50 km/hr. How much time (in seconds) will they take to cross each other?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 18.
Relative speed = 50 + 58 = 108 km/hr = 30 km/hr
Total distance to be covered = 280 + 260 = 540 m
Time taken = 540/30 = 18 seconds
