A 270 metres long train running at the speed of 120 kmph crosses another train running in opposite direction at the speed of 80 kmph in 9 seconds. What is the length of the other train?
Length of 1st train=d1=270m
Let the length of other train=x metres=d2
Ans is 230 metre
Relative speed = (120 + 80) km/hr =>200km/hr
Let the length of the other train be x metres.
Then, (x + 270)/9=500/9
so length of other train =230 meter
