Two trains 200 metres and 100 metres in length are
running towards each other on parallel tracks, one at the rate 50 km/hr and another at 40 km/hr. In how many seconds will they be clear of each other from the moment they meet?Solution
Required time = Sum of the lengths of trains / Relative speed Relative speed = 50 + 40 = 90 kmph = (90 Ă— 5)/18 = 25 m/sec Required time = (200 + 100)/25 = 300/25 = 12 seconds
