Answer:

2. y = 25 km

Step-by-step explanation:

To find the dimensions, write a proportion. A proportion is an equation of ratios.

[tex]\frac{scale}{factor} = \frac{Actual}{Model}[/tex]

Then solve for the unknown value by cross multiplying.

2. [tex]\frac{2}{5} = \frac{10}{y}[/tex]

2y = 5*10

2y = 50

y = 25
