Question
Train ‘A’ running with a speed of 108 km/hr crosses
a vertical pole in 8 seconds. Find the approx. time taken by the train ‘A’ to cross a train ‘B’ whose length is 130 metres less than that of train ‘A’ and whose speed is 1/5 more than that of train ‘A’ if both are running in opposite direction.Solution
Speed of train ‘A’ = 108 × (5/18) = 30 m/sec Length of train ‘A’ = 30 × 8 = 240 metres Length of train ‘B’ = 390 – 240 = 110 metres Speed of train ‘B’ = 30 + (30/5) = 36 m/sec Required time taken = (240 + 110)/(30 + 36) = 5.30 = 5 seconds
