Step-by-step explanation:
<u><em>The picture of the question in the attached figure</em></u>
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or 
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
Let
x ----> the time in hours
y ----> the distance in miles
<em>Find the value of k</em>
For the point (4,2268)

The slope represent the speed of the airplane
so
The linear equation is

Part 1 :
The point (0,0) represents the starting point of the aircraft, when the time and distance are equal to zero. The cruising starts when time t = 0.
Part 2 :
The point (4, 2268) represents the plane after 4 hours of cruise , and shows it has traveled a distance of 2268 miles after 4 hours
q= 6
r= 7
work--
Multiply 1st column by -2:
-30q+8r=-124
5q+8r=86
Subtract 2nd column from the first column:
-35q= -210
Solve for q:
q=6
Subtract q=6 by any of the two equations, so:
-30q+8r=-124
-30*6+8r=-124
Solve for r:
r=7
How many 50 miles are in 600 miles :
600 miles / 50 miles = 12
There are 12 slices of 50 miles in 600 miles.
1 slice of 50 miles equals 0.5 inch
(1 slice × 0.5 inch = 0.5 inch)
so
12 slices of 50 miles equals 6 inches
(12 slices × 0.5 inch = 6 inches)
The lenght of the freeway on the map is 6 inches.
Answer:
200 X 5 = 1000 square feet
Step-by-step explanation:
V = L x W x H
