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 500 meters and both trains running in the opposite direction.
Let speed of train B be ‘x’ km/hr. According to question, => 30(46 + x) × (5/18) = 500 => 1380 + 30x = 1800 => 30x = 420 => x = 14 km/hr.
