Question
Train A takes 45 minutes more than train B to travel a
distance of 450 km. Due to engine trouble speed of train B falls by a quarter, so it takes 30 minutes more than Train A to complete the same journey. What is the speed of Train A (in km/hr)?Solution
let the speed of train A is x and speed of train B is 4y 450/x - 450/4y = 45 minutes(3/4) hour ------(1) 450/3y - 450x = 30 minutes (1/2) hour ------(2) on solving example (1) and (2) we get y = 30 and x = 100 km/hr Sped of A = 100 km/hr
