Answer:

$\displaystyle d = 18$

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction

Left to Right

Algebra I

Coordinates (x, y)

Algebra II

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

Step-by-step explanation:

Step 1: Define

Identify

Point (21, 13)

Point (3, 13)

Step 2: Find distance d

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

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(3-21)^2+(13-13)^2}$
[√Radical] (Parenthesis) Subtract: $\displaystyle d = \sqrt{(-18)^2+(0)^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{324+0}$
[√Radical] Add: $\displaystyle d = \sqrt{324}$
[√Radical] Evaluate: $\displaystyle d = 18$

A light plane flew from its home base to an airport 255 miles away. With a head wind, the trip took 1.7 hours. The return

ryzh [129]

The speed from home base to airport was:
$v=255miles/1.7h\ /:1.7\\v=150mph$
The speed from airport to home base was:
$v=255miles/1.5h\ /:1.5\\v=170mph$
Average speed of plane was:
$\frac{170mph+150mph}{2}=160mph$
Average speed of wind was:
$x\ -\ wind\ speed\ (mph)\\150+x=170-x\ /+x\\150+2x=170\ /-150\\2x=20\ /:2\\x=10$
Answer: Average speed of plane was 160mph and average speed of wind was 10mph.

I hope I helped :D
