Two trains of same length are running in parallel tracks in opposite directions with speeds 65 km/h and 85 km/h respectively. They cross each other in 6 s . The length of each train is ?
-
- 100 m
- 115 m
- 125 m
- 150 m
Correct Option: C
Let length of each train be L m.
Then. (65 + 85 ) x 5/18 = (L + L)/6
⇒ (150 x 5 x 6)/18 = 2L
⇒ 2L = 250
∴ L = 125 m
