Find the scale for how many miles per inch are on the map:
270 miles / 4.5 inches = 60 miles per inch.
On the map every 1 inch equals 60 miles.
12 inches x 60 miles per inch = 720 miles total.
City B and City C are 720 miles apart
Midpoint is : (x1 + x2) / 2 , (y1 + y2) / 2
(-1,3)....x1 = -1 and y1 = 3
(7,-1)...x2 = 7 and y2 = -1
now we sub and solve
m = (-1 + 7)/2 , (3 - 1) / 2
m = (6/2, 2/2)
m = (3,1) <===
