Two express trains 200 meters and 150 meters long are moving in the same direction at 72 km/h and 54 km/h respectively. Find the time taken by the faster train to cross the slower train completely.
A. 80 seconds
B. 60 seconds
C. 70 seconds
D. 90 seconds
Answer: Option C
Solution (By JKSSB Mock Tests)
Total distance = 200 + 150 = 350 meters. Relative speed in same direction = 72 - 54 = 18 km/h = 5 m/s. Time taken = 350 / 5 = 70 seconds.
Two trains 140 meters and 160 meters long are tracking on parallel routes in opposite directions at 40 km/h and 50 km/h respectively. How long do they take to clear each other?
