Train A running at a speed of 31 km/hr crosses train B in 20 seconds. Find the speed of train B (in km/hr), if the sum of the length of train A and B is 250 meters and both trains running in the opposite direction.
Let speed of train B be ‘x’ km/hr. According to question, => 20(31 + x) × (5/18) = 250 => 620 + 20x = 900 => 20x = 280 => x = 14 km/hr
