Question
Two trains, A and B, start simultaneously from station X towards station Y. Train A travels the first 60 km at its original speed, then reduces its speed by 25% and reaches station Y at 10 A.M. Train B travels the first 90 km at its original speed, then reduces its speed by 25% and reaches station Y at 9:45 A.M. If both trains had maintained their original speeds throughout the journey, they would have arrived at station Y at 8:30 A.M.
What is the sum of the time taken by train A and train B to cover the distance between station X and station Y if both trains travel the entire distance at their original speeds?
