Step-by-step explanation:
... speed = distance/time
Fill in the given values:
... speed = (3/8 mi)/(3/5 h)
_____
<em>Comment on units</em>
You can use the units to provide both guidance and assurance. You know speed is generally expressed in <em>miles per hour</em>. If you consider "per" to mean "divided by", this expression of units tells you speed is calculated by dividing miles by hours.
If you leave the units with the numbers, as we have above, they enter into the calculation the same way any variable might. You can do the arithemetic with the numbers, and you can indicate the arithmetic with the units (just as you would with any variables). Here, the result of evaluating the equation would be ...
The fact that the units come out mi/h (the units of speed) provides assurance that you probably did the math correctly.

Step-by-step explanation:
To create a 3 by 3 magic square using nine of the ten numbers
20,21,22,22,23,24,25,26,27,28 and 29
In order to achieve a 3 by 3 magic square table we will pick Nine consecutive numbers out of the ten numbers given and apply the format below
n+1,n-4,n+3,n+2,n,n-2,n-3,n+4,n-1
we will take n = 24
attached below is the magic square
