Question
Train ‘A’ travelling with a speed of 75 km/h can
cross a pole in 15 seconds. If the length of train ‘B’ is 24% less than that of train ‘A’ and it can cross a pole in 15 seconds then speed (in km/h) of train ‘B’ is:Solution
Speed of train ‘A’ = 75 × (5/18) = (125/6) m/s Length of train ‘A’ = (125/6) × 15 = 312.5 metres Length of train ‘B’ = 0.76 × 312.5 = 237.5 metres Speed of train ‘B’ = (237.5/15) × (18/5) = 57 km/h
