Question
Train X running at a speed of 35 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 550 meters and both trains running in the opposite direction.Solution
Let speed of train Y be 'a' km/hr. According to question, => 18(35 + a) × (5/18) = 550 => 630 + 18a = 1980 => 18a = 1350 => a = 75 km/hr
