Let the speed ratio of two trains be 5x and 8x respectively. Let the ratio of their lengths be 4y and 3y respectively. Speed = Distance / Time When travelling in same directions, => (8x-5x) = (4y+3y)/20 => 3x = 7y/20 Hence, we don’t have any value given here so the answer will be cannot be determined.
