    Train A running at a speed of 46 km/hr crosses train B

    in 30 seconds. Find the speed of train B (in km/hr), if the sum of the length of train A and B is 550 meters and both trains running in the opposite direction.
    A 19 km/hr Correct Answer Incorrect Answer
    B 13 km/hr Correct Answer Incorrect Answer
    C 20 km/hr Correct Answer Incorrect Answer
    D 14 km/hr Correct Answer Incorrect Answer

    Solution

    Let speed of train B be ‘x’ km/hr. According to question, => 30(46 + x) × (5/18) = 550 => 1380 + 30x = 1980 => 30x = 600 => x = 20 km/hr
