A 270 M Long Train Running At The Speed Of 120 Km/hr Crosses Another Train Running In Opposite Direction At The Speed Of 80 Km/hr In 9 Sec. What Is The Length Of The Other Train?

Answer»

Relative SPEED = 120 + 80 = 200 km/hr.
= 200 * 5/18 = 500/9 m/sec.
Let the length of the other train be x m.
Then, (x + 270)/9 = 500/9 => x = 230.

Relative speed = 120 + 80 = 200 km/hr.
= 200 * 5/18 = 500/9 m/sec.
Let the length of the other train be x m.
