Two trains, 148 m and 152 m long, are running towards each other on parallel lines at 62 km/h and 46 km/h, respectively. In what time will they be clear of each other from the moment they meet?
10 sec
Relative speed = 62 + 46 = 108 km/h = 108 × 1000 / 3600 = 30 m/s. The total length of the trains is 148 + 152 = 300 m. Time taken = Distance / Speed = 300 / 30 = 10 sec.
