Which speed is the fastest? A 18 feet in 20 minutes B 90 feet in 2.5 hours C 20 yards in 1.5 hours D 3 2/3 yards in 15 minutes
1 answer:
To solve, put each answer in terms of ft/min. Do this by converting all distances to feet and times to minutes, the dividing feet by minutes. A) 
ft/min. B) To get 2.5 hrs to mins, multiply by 60. 
ft/min. C) To get feet from yards, multiply yards by 3. 
ft/min. D) 
ft/min. Now compare the fractions to determine the largest and fastest is 9/10 ft/min, or A.

The quadrilateral formed by this process will always be a parallelogram
<h3>Quadrilaterals</h3>A quadrilateral is simply any polygon that has four sides and four corners.
Common examples are:
- Square
- Rectangle
- Rhombus
- Kite
- Trapezoid
- Rhombus
- Parallelogram
A square is drawn at the coordinates:
(0,0), (6,0), (0,6) and (6,6)
The midpoints of the square sides are at the following coordinates:
(0,3), (3,6), (6,3) and (3,0)
When the points of the midpoints are joined together, they form a parallelogram
<h3>Figure 2</h3>A trapezoid is drawn at the coordinates:
(0,0), (2,6), (8,6) and (10,0)
The midpoints of the square sides are at the following coordinates:
(5,0), (5,6), (1,3) and (9,3)
When the points of the midpoints are joined together, they form a parallelogram
Hence, the quadrilateral formed by this process will always be a parallelogram
