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.

Forget this above mentioned method

one man cover 600 m in 5 min thn in 60 min (1 hour)how much he cover

( 60 x 600 ) / 5 = 7200 m = 7200 / 1000 = 7.2 km / hour

1 km = 1000 m

one man cover 600 m in 5 min thn in 60 min (1 hour)how much he cover

( 60 x 600 ) / 5 = 7200 m = 7200 / 1000 = 7.2 km / hour

1 km = 1000 m

Hi Vidu and Sushree,

You questions is from where did 60 come?

Please concentrate on the unit name mentioned along with the numbers.

Speed = Distance/Time

Here Distance = 600 meters and Time = 5 mins.

Therefore, Speed = 600/5 meters/minutes.

We have to write it as in terms of

So, Speed = 600/(5 x 60 sec) meters/seconds.

I strongly suggest all newbies to go through the basic formulas before posting your doubts here. So, kindly go through the basic

Have a nice day!
