99 km ... 9 liters
x km ... 12 liters

If the relationship is proportional, we have

$\frac{99}{x} = \frac{9}{12}$

from where

$x = \frac{99*12}{9}= \frac{1188}{9}=\bold{132}$

The answer is 132 kilometers.

The length of a rectangle is 10 yards more than the width. If the perimeter is 68 yards, what are the length and width?

quester [9]

Divide the perimeter by 2, this will give you the sum of one length and one width.

68/2 = 34 yards

Now the length is 10 yards more, so subtract 10 from the 34 and divide by 2 again:

34 - 10 = 24

24 /2 = 12

The width is 12 yards.

The length is 12 + 10 = 22 yards.
