Question
Two trains 160 metres and 140 metres in length are
running towards each other on parallel tracks, one at the rate 52 km/hr and another at 38 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 = 52 + 38 = 90 kmph = (90 × 5)/18 = 25 m/sec Required time = (160 + 140)/25 = 300/25 = 12 seconds
