Two trains are moving in opposite directions at speeds of 50 km/h and 110 km/h. The length of one train is 500 m. The time taken by them to cross each other is 12 seconds. The length (in m) of the other train, correct to 2 decimal places, is:
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 33.33.
Relative speed = 50 + 110 = 160 km/h = (160 × 1000) / 3600 = 44.44 m/s
Time = 12 sec
Total distance = 44.44 × 12 = 533.33 m
Length of one train = 500 m
Length of other train = 533.33 − 500 = 33.33 m
