Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Point (11, 4) → x₁ = 11, y₁ = 4

Point (5, 8) → x₂ = 5, y₂ = 8

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(5-11)^2+(8-4)^2}$
[√Radical] (Parenthesis) Subtract: $\displaystyle d = \sqrt{(-6)^2+(4)^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{36+16}$
[√Radical] Add: $\displaystyle d = \sqrt{52}$
[√Radical] Simplify: $\displaystyle d = 2\sqrt{13}$

The scale on a map reads 1/4

slamgirl [31]

Answer:

550 miles.

Step-by-step explanation:

First, we know that each 1,4 (quarter) of an inch equals 50 miles. and we know that four 1,4s equals one. so, using that information, we have 2 3/4. so the 2 has 8 quarters, and then we have 3 quarters left. so we add the 8 quarter's and the 3 quarter's, to get 11. and since each quarter is equal to 50 miles, we multiply 50 by 11.
