Solved.

The formula is SELF-EXPLANATORY.

It is as simple, as a cucumber, or as 3 - 1 = 2.

When the kid asks, the car has already traveled 50.75 miles.
They need to travel another 65x miles (due to the formula distance = rate*time) where x is the extra number of hours needed to travel this distance.
The total distance is 65x+50.75
Set this equal to 668.25 and solve for x.

65x+50.75 = 668.25
65x = 668.25-50.75
65x = 617.5
x = 617.5/65
x = 9.5 hours is the answer.

Check:
65*x+50.75 = 65*9.5+50.75 = 668.25
This confirms the answer.
