Question
Train X running at a speed of 36 km/hr crosses train Y
in 18 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. TYPE 46Solution
Let speed of train Y be 'a' km/hr. According to question, => 18(36 + a) × (5/18) = 500 => 648 + 18a = 1800 => 18a = 1152 => a = 64 km/hr
