Answer 2

The distance between his house and post office is  1800 meter.

Explanation:

Given:

10 minutes to reach the post office from his house rickshaw.

The speed of the rickshaw is 3m/s.

To Find:

The distance between his house and post office.

Solution:

As given,10 minutes to reach the post office from his house rickshaw.

Time taken to reach the post office from his house rickshaw

                                                                    = 10 minutes

                                                                     $=10\times 60 =600 \ seconds$

As given, the speed of the rickshaw is 3 m/s.  

       The speed of the rickshaw= 3 m/s.  

$The\ speed\ of\ the\ rickshaw=\frac{The\ distance\ between\ his\ house\ and \ post \ office}{Time\ taken\ to\ reach\ the\ post\ office\ from\ his\ house\ rickshaw}$

                                       $3=\frac{The\ distance\ between\ his\ house\ and \ post \ office}{600}$

$The\ distance\ between\ his\ house\ and \ post \ office=3\times 600$

                                                                              $=1800\ meter$

Thus,the distance between his house and post office is  1800 meter.
