<pre>
If they arrived home at the same time, and the sister was walking 30 minutes, while the brother
was walking 40 minutes, it means that the brother had walking 40-30 = 10 minutes when the sister
left the school.


In 10 minutes, the brother covered {{{10/40}}} = {{{1/4}}}  of the distance from the school to home.    <U>ANSWER</U>
