Answer:
They travel 5 miles to get back to Amanda's house.
Step-by-step explanation:
Using the pythagorean theorem, we know that:
[tex]3^{2} +4^{2} =c^{2}[/tex].
This simplifies down to:
[tex]25 = c^{2}[/tex]
Take the square root of both sides to find c:
[tex]\sqrt{25} =c[/tex]
This simplifies down to: c = 5 miles.
