Question
Train ‘A’ can cross a pole in 10 seconds and a 50
metre long platform in 12 seconds. If the ratio of length of train ‘A’ and train ‘B’ is 2:5, respectively, then find the time taken by train ‘B’ to cross a pole with a speed of 25 m/s.Solution
Let the length and speed of the train ‘A’ be ‘l’ metre and ‘s’ m/s, respectively. According to question, l = 10s Also, 12s = 10s + 50 Or, 2s = 50 Or, s = 25 Therefore, length of train ‘A’ = 10s = 250 metres Length of train ‘B’ = 250 × (5/2) = 625 metres Required time taken = 625 ÷ 25 = 25 second
