Final answer:
To find the unit rate in kilograms per foot, divide 1/3 by 2/3.
Step-by-step explanation:
To find the unit rate, we need to divide the given quantities. The unit rate is the amount of one quantity per one unit of another quantity. In this case, the given quantities are 1/3 kilograms and 2/3 foot. To find the unit rate in kilograms per foot, we divide 1/3 by 2/3.
Dividing fractions involves multiplying the first fraction by the reciprocal of the second fraction. So, (1/3) / (2/3) = (1/3) * (3/2) = 1/2.
Therefore, the unit rate is 1/2 kilograms per foot.
