Question

Angela wants to walk her dog along the route shown with the arrows. How far did she walk if the following is true?

Answer 1

that's pretty easy
all the lengths are given
A st is 1 mile long that's 1
then 0.5 miles + 0.5 miles of 2nd st that's 1
total 1+1 =2
then as 3rd st =2nd st
it will be 2+05 =2.5
then again walk of 1 mile that is 2.5+1 =3.5
then 2nd st's 0.5 and return walk of 1 mile
that's 3.5+0.5=1 =5

Answer 2

and remember
perpendicular bisectr divides line in 2 same parts~
