1.

A person crosses a 600 m long street in 5 minutes. What is his speed in km per hour?

Answer: Option

Explanation:

Speed = | 600 | m/sec. | |

5 x 60 |

= 2 m/sec.

Converting m/sec to km/hr (see important formulas section)

= | 2 x | 18 | km/hr | ||

5 |

= 7.2 km/hr.

2.

An aeroplane covers a certain distance at a speed of 240 kmph in 5 hours. To cover the same distance in 1 hours, it must travel at a speed of:

Answer: Option

Explanation:

Distance = (240 x 5) = 1200 km.

Speed = Distance/Time

Speed = 1200/(5/3) km/hr. [We can write 1 hours as 5/3 hours]

Required speed = | 1200 x | 3 | km/hr | = 720 km/hr. | |

3.

If a person walks at 14 km/hr instead of 10 km/hr, he would have walked 20 km more. The actual distance travelled by him is:

Answer: Option

Explanation:

Let the actual distance travelled be *x* km.

Then, | x |
= | x + 20 |

10 | 14 |

14*x* = 10*x* + 200

4*x* = 200

*x* = 50 km.

4.

A train can travel 50% faster than a car. Both start from point A at the same time and reach point B 75 kms away from A at the same time. On the way, however, the train lost about 12.5 minutes while stopping at the stations. The speed of the car is:

Answer: Option

Explanation:

Let speed of the car be *x* kmph.

Then, speed of the train = | 150 | x |
= | 3 | x |
kmph. | |

100 | 2 |

75 | - | 75 | = | 125 | |

(3/2)x |
10 x 60 |

75 | - | 50 | = | 5 | |

5.

Excluding stoppages, the speed of a bus is 54 kmph and including stoppages, it is 45 kmph. For how many minutes does the bus stop per hour?

Answer: Option

Explanation:

Due to stoppages, it covers 9 km less.

Time taken to cover 9 km = | 9 | x 60 | min | = 10 min. | |

54 |
