please help me!!!!!! will mark brainliest mathhhhhhh!!!!!

Answer:
257.4 mi
Step-by-step explanation:
d= √(x₂-x₁)²+(y₂-y₁)²
d= √(8.5-3)²+(14.5-2.5)²=
d= √(5.5)²+(12)²=
d= √30.25+144=
d= √174.25=
d=13.2
since 1 unit is equal to 19.5 miles you can use the equation below where c is the distance between the two cities and d is the distance between the two points.
c=19.5d
c=19.5(13.2)
c=257.4 mi
