Two trains are moving in opposite directions at speeds of 140 km/h and 80 km/h. The length of one train is 340 m. The time taken by them to cross each other is 11 seconds. The length (in m) of the other train, correct to 2 decimal places, is:
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 332.22
Speed = Distance/time
(140 + 80) × 5/18 = (340 + L)/11
⇒ 220 × 5/18 = (340 + L)/11
⇒ 672.22 = 340 + L
L = 332.22
