Marks: +1, -0

Two trains of lengths 150 m and 180 m respectively are running in opposite directions on parallel tracks. If their speeds be 50 km/hr and 58 km/hr respectively, in what time will they cross each other

30 seconds
15 seconds
22 seconds
11 seconds

Validate

Solution:

Trains are moving in the opposite directions,
Relative distance = (150 + 180) = 330 m
Relative speed = (50 + 58) x

5/18

m/sec = 108 x

5/18

m/sec = 30 m/sec
Relative time can be written as, T =

D/S

330/30

= 11 seconds
Hence, option D is the correct answer.
