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
