Answer:
[tex]\frac{24}{35}mi[/tex]
Step-by-step explanation:
Area = length • width
area = [tex]\frac{3}{5}mi^{2}[/tex]
length = [tex]\frac{7}{8} mi[/tex]
width = x
[tex]\frac{3}{5} = \frac{7}{8} x[/tex] multiply both sides by [tex]\frac{8}{7}[/tex] (the reciprocal of [tex]\frac{7}{8}[/tex])
[tex](\frac{8}{7})(\frac{3}{5}) = x[/tex]
x = [tex]\frac{24}{35}[/tex]
