Answer:

0.3125

Step-by-step explanation:

Use definition of geometric probability:

[tex]P=\dfrac{\text{Desired Length}}{\text{Total Length}}[/tex]

In your case,

Total Length = 8 miles

Desired Length = 7 - 4.5 = 2.5 miles,

so the probability is

[tex]P=\dfrac{2.5}{8}=\dfrac{25}{80}=\dfrac{5}{16}=0.3125[/tex]
