Answer:

r(x) + x = 762

Step-by-step explanation:

We know that the addition of the completed miles and the remaining miles is the total distance to cover.

remaining miles + completed miles = total miles

If we defined the remaining distance as "r(x)" and the already completed distance as "x":

r(x) + x = 762

This equation express the relationship between the completed miles and the remaining miles.
