Answer:

The distance between the cities is 81 miles

Step-by-step explanation:

* Lets explain how to find a distance between two points

- The distance between the two pints [tex](x_{1},y_{1})[/tex] and

  [tex](x_{2},y_{2})[/tex] is

  [tex]d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]

* Lets solve the problem

∵ City A located at point (55 , 11)

∵ City B located at point (116 , 65)

- Let point [tex](x_{1},y_{1})[/tex] = (55 , 11) and point

 [tex](x_{2},y_{2})[/tex] = (116 , 65)

∴ [tex]x_{1}=55[/tex] and [tex]x_{2}=116[/tex]

∴ [tex]y_{1}=11[/tex] and [tex]y_{2}=65[/tex]

- By using the rule above

∴ [tex]d=\sqrt{(116-55)^{2}+(65-11)^{2}}=\sqrt{(61)^{2}+(54)^{2}}=81.47[/tex]

The distance between the cities is 81 miles
