Q. |
## A train running at the speed of 60 km/hr crosses a pole in 9 seconds. What is the length of the train? |

A. | 150 m |

B. | 120 m |

C. | 180 m |

D. | 200 m |

Answer» A. 150 m | |

Explanation: We know that, Distance = Speed * Time. Here, Distance is the length of the train and time = 9 seconds. We convert speed from km/hr to m/sec by multiplying by 5/18, so Speed = 60*(5/18) m/sec = 50/3 m/sec. Therefore, Distance = Speed * Time = 50/3 m/sec * 9 sec = 150 m. So, the length of the train is 150 m. |
