Question

Two trains running at a speed of 68 km/hr and 56 km/hr respectively but in the same direction. The faster train a man sitting in the slow train in 60 Seconds find the length of the fast train. KINDLY DO IT QUICKLY N U CAN ALSO ATTACH A PIC OF THIS ANSWER

Answer 1

Given that trains are moving in the same direction.

We know that Relative speed of the train = (x - y) km/hr.

                                                                     = (68 - 56) k/hr

                                                                     = 12 km/hr

                                                                     = 12 * 5/18

                                                                     = 60/18

                                                                     = 10/3 m/sec


Now,

The length of the fast train = Relative speed * Time taken by train to pass

                                             = 10/3 * 60

                                             = 200m.


Therefore the length of the fast train = 200m.


Hope this helps!
