Two trains 100 meters and 120 meters long are running in the same direction at speeds of 72 km/h and 54 km/h respectively. In how much time will the faster train cross the slower train completely?
A. 44 seconds
B. 36 seconds
C. 48 seconds
D. 40 seconds
Answer: Option A
Solution (By JKSSB Mock Tests)
Total distance = 100 + 120 = 220 meters. Relative speed = 72 - 54 = 18 km/h = 5 m/s. Time taken = 220 / 5 = 44 seconds.
