If you would like to know what is your average speed, you can calculate this using the following steps:
1 3/4 miles = 7/4 miles ...half an hour
7/4 miles * 2 = 7/2 miles = 3 1/2 miles ... one hour
Result: Your average speed is 3 1/2 miles per hour.
The answer is: "4" .

<u>Note</u>: The question asks for a whole number.
"The area of the triangle above will equal one half of a rectangle that is 5 units long and <u> 4 </u><u /> units wide. (Input only whole numbers, such as 8.).
______________________________________________________
<u>Note</u>: The diagram shows a "right triangle" ; which would be "one-half" of a rectangle, with units of "length" being "5 units" (as mentioned in this very question prompt; and a width of "4" units (as shown in the diagram; hence the answer is "4" units).
Furthermore, the formula/equation for the area, "A" , of a triangle is:
A = (1/2) * b * h ;
that is:
Area = (1/2) * (base length) * (perpendicular height).

As such, the answer, "4" (units) makes sense.

Step-by-step explanation:
X-2y=5 ; 2x-4y=10
• x - 2y = 5 • 2x -4y = 10
-2y = -x+5 -4y= -2x +10
y1 = ½x - 5/2 y2 = ½x -5/2
• => y1 = y2
½x -5/2 = ½x -5/2
the systems have no solution
