<p>thanks for the site man.. gr8 help... what this thing of b=0 n all...</p>
<p>If it takes 4 men 8 hours to dig a hole, how many hours will it take 2 men to dig a half of a hole?</p>
<p>Inverse proportion.</p>
<p>4=k/8</p>
<p>32=k</p>
<p>Now for two men . . . </p>
<p>2=k/hours</p>
<p>2=k/h</p>
<p>2=32/h</p>
<p>2h=32</p>
<p>h=16</p>
<p>And for half a hole. . . </p>
<p>h=8</p>
<p>It'll take em 8 hours.</p>
<p>think about it this way.... if 4 men dig a hole in 8 hours, how many hours will 1 men dig? Using common sense, 1 man will take longer time to dig a hole than 4 men do, so the no. of hours taken to dig a hole by a man is definitely more than the no. of hours taken by 4. Unless you have superman powers, u will finish digging a hole in 2 hours when it takes 8 hours for 4 men to dig this same hole. </p>
<p>Inversely proportional!!!</p>
