Scale : 1 inch = 30 miles
So, the ratio between the distance on the map and the real distance is 1:30
When a quantity increase/decrease in a ratio, the other one increase/decrease respectively.
Call the miles we have to go : x
1:30 = 4.5:x
(1x4.5):(30x4.5) = 4.5 : x
4.5 : 135 = 4.5 : x
So, x = 135 => We have to go 135 miles to get to the place we want to go.

Answer:
P(6, 1)
Step-by-step explanation:
Point P is the weighted average of the end point coordinates. The weights are the reverse of the order of the segment lengths:
P = (2A +3B)/(2+3)
P = (2(-3, -2) +3(12, 3))/5 = (-6+36, -4+9)/5
P = (6, 1)
