Rajdhani Express train of length 108 m is running at the speed of 128 km/h.
Another train of length 148 m is standing at the station
Concept used:
Distance = speed × time
Calculation:
Total distance is , 108 + 148 = 256 m
⇒ Speed = 128 km/h = 128 × 5/18 m/s = 320/9 m/s
So, time = distance /speed
⇒ 256/ (320/9) = (256 × 9)/320 = 7.2 sec
∴ The correct option is 4
