Question
If the ratio of speed of train C and Train D is 5:8 and
takes 20 seconds to completely cross each other in same direction. If the ratio of their length is 4:3 then find the speed of slow train.Solution
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.
