Question

the distance between City a and City b is 200 mi. on a certain wall map this is represented by the length of 1.7 ft. On the map how many feet would there be between City c and City d two cities that are actually 400 mi apart?

Answer 1

Given that:

the distance between City a and City b is 200 mi. on a certain wall map this is represented by the length of 1.7 ft.

So:

$\begin{gathered} 200\text{ mi=1.7 ft } \\ 1\text{ mi=}\frac{1.7}{200}ft \end{gathered}$

between City c and City d two cities that are actually 400 mi apart?:

So for 400 mi.

$\begin{gathered} 1\text{ mi=}\frac{1.7}{200}ft \\ 400\text{ mi=400}\times\frac{1.7}{200}ft \\ 400mi=2\times1.7ft \\ 400\text{ mi=3.4ft} \end{gathered}$

So 3.4 feet would there be between City c and City d two cities that are actually 400 mi apart
