    Question

    A train moving at a speed of β€˜x’ km/h crosses a

    signal post in 22 seconds and then passes a 300 metre long bridge in 40 seconds. Calculate the total distance it would cover in 10 hours.
    A 600 km Correct Answer Incorrect Answer
    B 210 km Correct Answer Incorrect Answer
    C 500 km Correct Answer Incorrect Answer
    D 255 km Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let speed of train = y m/s So, length of train = 22 Γ— y = 22y metres According to question: (22y + 300) = 40y Or, 18y = 300 Or, y = 16.67 m/s So, x = 16.67 Γ— 18/5 = 60 km/h Desired distance = 60 Γ— 10 = 600 km
