in 24 seconds. Find the speed of train B (in km/hr), if the sum of the length of train A and B is 420 meters and both trains running in the opposite direction.Solution
Let speed of train B be ‘x’ km/hr. According to question, => 24(32 + x) × (5/18) = 420 => 768 + 24x = 1512 => 24x = 744 => x = 31 km/hr
