To solve the equation 6x = 9, we need to find the missing value which is represented by x.
Given that the pace is 6 miles per hour and the total distance run is 9 miles, we can relate the two by the equation 6x = 9.
To find x, we divide both sides of the equation by 6:
(6x)/6 = 9/6
x = 3/2
The missing value x represents the time it took to run the 9 miles.
Therefore, the unit that should be used for the missing value is 2 for hours.
