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

Step-by-step explanation:

Step 1: Define

Point (5, -6)

Point (-3, 12)

Step 2: Find distance d

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

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(-3-5)^2+(12+6)^2}$
[√Radical] (Parenthesis) Subtract/Add: $\displaystyle d = \sqrt{(-8)^2+(18)^2}$
[√Radical] Evaluate Exponents: $\displaystyle d = \sqrt{64+324}$
[√Radical] Add: $\displaystyle d = \sqrt{388}$
[√Radical] Simplify: $\displaystyle d = 2\sqrt{97}$

a map has a scale of 3cm : 18 km. If riverside & Smithville are 54 km apart they are how far apart on the map?

Finger [1]

Alright! To solve this one you first have to find out what 1cm is equal to in km, to do that you have to divide 18km by 3cm:

[18 ÷ 3] = 6.

Now we know that 1cm is 6km. To find how far apart they are on the map you simply divide 54km by 6km:

[54 ÷ 6] = 9.

They are 9cm apart on the map.
