Answer:

23.1m

Step-by-step explanation:

we define x to be the actual distance, y to be the distance on map (y=15.4cm)

if the map scale is 3:750, then by definition of scaling, x and y must satisfy:

[tex] \frac{y}{x} = \frac{3}{750} = \frac{1}{150} [/tex]

we isolate x:

[tex]x = 150 \times y = 150 \times 15.4 = 2310cm = 23.1m[/tex]
