Question 1171182
<br>
******************<br>
Note to tutor @ikleyn....<br>
The new number of workers is 12, not 8....<br>
******************<br>
With inverse variation, if one of the two quantities changes by a factor of x, the other factor changes by a factor of 1/x.<br>
In the given problem, the number of workers changes by a factor of 12/18 = 2/3; that means the number of days changes by a factor of 3/2.<br>
ANSWER: 3(3/2) = 9/2 or 4.5 days<br>
