Final Answer

Thank you for the opportunity to help you with your question!

Their moving can be described as right triangle, so 8 miles and 5 miles are two legs and you need to find hypotenuse: c^2=8^2+5^2=64+25=89

c=sqrt(89)=9.4 miles

Please let me know if you need any clarification. I'm always happy to answer your questions.
