Answer: 
Step-by-step explanation:
It is important to remember that, by definition, proportional relationships have the following form:

Where "k" is the constant of proportionality.
We know that Maddy assume that the relation between the volume and the weight is proportional.
Then, let be "V" the volume in liters and "w" the weight in kilograms.
We can write the following equation:
So, if the boat of 555 liters weights 7.5 kilograms, we can find "k":

In order to solve the exercise, substitute the value of "k" and
into the equation and solve for "w". Then:
Answer:
(Unless I am understanding the question/lesson wrong I know how to do this)
Step-by-step explanation:
On the first set you can see that 1 is the time and 3 is the distance so you would go to the chart and where it says time you would go right one time and I think since it says distance you would be the point up 3 times to the chart would look like (1,3).
Hope this helps :)
