A 260 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 ?

A 260 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 ? Correct Answer 240 mts

Relative speed = 120 + 80 = 200 km/hr.= 200 x 5/18 = 500/9 m/sec.

Let the length of the other train be L mts.Then, (L + 260)/9 = 500/9 => L = 240 mts.
