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=}(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=}(1.7)/(200)ft \\ 400\text{ mi=400}*(1.7)/(200)ft \\ 400mi=2*1.7ft \\ 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
