A goods train runs at the speed of 72 kmph and crosses a 250 m long platform in 26 seconds. What is the length of the goods train?
**

##### Explanation

Speed = | 72 x | 5 | m/sec | = 20 m/sec. | |

18 |

Time = 26 sec.

Let the length of the train be *x* metres.

Then, | x + 250 |
= 20 |

26 |

*x* + 250 = 520

*x* = 270.
