Remark
You can use a method called unit analysis to solve this problem. You will use it many times in your education later on.
Solve
Now sort out the numbers in the numerator and those in the denominator and multiply them together.
<em><u>Numerator</u></em> 28 * 5280 * 1 * 1 = 147840
<em><u>Denominator:</u></em> 60 * 60 = 3600
Now divide the numerator by denominator
Answer = 147840 / 3600 = 41.1 Feet / second
28 miles per hour = 41.1 feet / second
Answer: (-1/2, 0) which is the same as saying (-0.5, 0)
================================================
Explanation:
The x coordinates of A and B are -2 and 1 respectively.
Add up those values to get -2+1 = -1
Then cut that result in half: -1/2 = -0.5
This is the x coordinate of the midpoint.
--------
Repeat for the y coordinates:
Add: 1 + (-1) = 0
Cut in half: 0/2 = 0
The y coordinate of the midpoint is 0
-------
Overall, the midpoint is located at (-1/2, 0) which is the same as writing (-0.5, 0). This is where the segment AB crosses the x axis.
