time would be the independent variable as it doesnt depend on the distance. distance is dependant as you need a certain amount of time to get somewhere..
If two objects have the same shape, they are called "similar." When two figures are similar, the ratios of the lengths of their corresponding sides are equal so the word would be ratio
Perimeter = (2)(length) + (2)(height)
Let's call the width x and the length y
Therefore perimeter = (2x)(2) + (5y)(2)= 4x+10y
2x÷(4x+10y) is the answer :)
Plot those coordinates on a graph and then join them together. if they do no join in a line its not linear.
