    in 30 seconds. Find the speed of train B (in km/hr), if the sum of the length of train A and B is 500 meters and both trains running in the opposite direction.
    A 19 km/hr Correct Answer Incorrect Answer

    C 20 km/hr Correct Answer Incorrect Answer
    D 14 km/hr Correct Answer Incorrect Answer
    E 24 km/hr Correct Answer Incorrect Answer

    Solution

    Let speed of train B be ‘x’ km/hr. According to question, => 30(41 + x) × (5/18) = 500 => 1230 + 30x = 1800 => 30x = 570 => x = 19 km/hr
