Speed of train A and train B is 90 km/hr and 36 km/hr respectively. They cross each other in 10 seconds when they are running in opposite directions. Length of train A is 50 meters more than length of train B. Which of the following can be find from the above given data.
i) Length of train A.
ii) Length of train B.
iii) Time taken by train A to cross a point
iv) Time taken by train B to cross a platform of length 350m.
Let length of first train be L1& length of 2nd train be L2. So (90+36)×5/18 = (L1+L2)/10 L1+L2 = 350m & L1- L2= 50m Hence L1 = 200m & L2 = 150m i) Already found ii) Already found iii) Time taken by train A to cross a point = 200m/90kmph = 200m/(25m/s) = 8 sec iv) Time taken by train B to cross a platform of length 350m = (350+150)m/36kmph = 500m/(10m/s) = 50 sec Hence all values can be find by given data so correct ans is option (d).
