Given :
On a number line, suppose the coordinate of A is 0, and AR = 15.
To Find :
the possible coordinates of the midpoint of AR.
Solution :
Their can be two points R which is at a distance of 15 units from the A .
One is -15 and other is 15.
Now, mid-point of A(0) and R(-15) is M (-7/2).
Also, mid-point of A(0) and R(15) is M (7/2).
Therefore, possible coordinates of the midpoint of AR is 7/2 , -7/2.
Hence, this is the required solution.

Step-by-step explanation:
To find out how long will it take for Joe and Bill to finish building the wall together, first find their individual work rates in feet per hour:
Bill:

Joe:

Their combined work rate is:

Then, divide the total size of the wall by their work rate to find the time spent to finish it:

Answer: 125 miles
if you do the math you will get the same answer.
