Two trains Z and X of lengths 380 meters and 610 meters respectively, are running in the same direction on parallel tracks. If the speeds of Z and X are 49 km/h and 82 km/h respectively, then what will be the time taken by them to cross each other?
Answer & explanation
Correct answer: option 2
Relative speed = 82 - 49
= 33 km/h
Distance = 380 + 610 = 990 meter
D = S × T
T = \(\frac{990}{33 × \frac{5}{18}}\) = 108 seconds
