Question
Train M, βxβ metres long crosses (x β 34) metres
long platform in 15 seconds while train N having the length (x + 34) metres crosses the same platform in 20 seconds. If the speeds of both trains are same then find the value of βxβ.Solution
Total distance travelled by train M = (2x β 34) m Total distance travelled by train N = (x + 34 + x β 34) = 2x m According to question, => (2x β 34)/15 = 2x/20 => 40x β 680 = 30x => 10x = 680 => x = 68 m
