The trip will be 4.67 inches on the map.

Step-by-step explanation:

Given,

Actual distance of Dallas to San Diego = 1400 miles

Scale on map;

1 inch = 300 miles

Ratio of scale on map = 1:300

Let,

x represent the distance from Dallas to San Diego.

Ratio of distance on map to actual distance = x:1400

Using proportion;

Ratio of scale on map :: Ratio of distance on map to actual distance

[tex]1:300::x:1400[/tex]

Product of mean = Product of extreme

[tex]300*x=1400*1\\300x=1400[/tex]

Dividing both sides by 300

[tex]\frac{300x}{300}=\frac{1400}{300}\\x=4.67[/tex]

The trip will be 4.67 inches on the map.
