If David walks 1/2 mile in 1/4 hour, then how fast does David walk in one hour? ( In other words what is Davids unit rate?)

Answers

Answer 1

Answer: 1/2 mile in 1/4 hour |just multiply by 4

4 * 1/2 miles in 4 * 1/4 hour

2 miles in 1 hour

Davids walked 2 miles per hour (his velocity was 2mph)

Here are the vertices of rectangle FROG: (-2,5),(-2,1),(6,5),(6,1). Find the perimeter of this rectangle. If you get stuck, try plotting the points on a coordinate plane. For the rectangle FROG, the perimeter is . Find the area of the rectangle FROG. For the rectangle FROG, the area is

Answers

The area and the perimeter of the rectangle FROG is evaluated as:

Area(FROG) = $32 \: \rm unit^2$
Perimeter(FROG) = $64\: \rm units$

How to find the area and the perimeter of a rectangle?

For a rectangle with length and width L and W units, we get:

Area of the rectangle = $L * W \: \rm unit^2$
Perimeter of the rectangle = $2(L + W) \: \rm unit^2$

What is the distance between two points ( p,q) and (x,y)?

The shortest distance(straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:

$D = √((x-p)^2 + (y-q)^2) \: \rm units.$

The coordinates of the points of the rectangle FROG are given as:

F(-2,5), R(-2,1), G(6,5), and O(6,1) (from its plot, as given below)

FR and RO are length and width pair(we can call any one of them as length and other as width) of the considered rectangle as they are adjacent to each other.

We denote length of a line segment AB by |AB|

Thus, we get:

Length of the rectangle = |FR| = $√((-2-(-2))^2 + (1 - 5)^2 ) = 4$ units
Width of the rectangle = |RO| = $√((6-(-2))^2 + (1 - 1)^2 ) = √(64) = 8 \: \rm units$
