Question
Train X running at a speed of 30 km/hr crosses train Y
in 15 seconds. Find the speed of train Y (in km/hr), if the sum of the length of train X and Y is 500 meters and both trains running in the opposite direction.Solution
Let speed of train Y be 'a' km/hr. According to question, => 15(30 + a) × (5/18) = 500 => 450 + 15a = 1800 => 15a = 1350 => a = 90 km/hr
