Pass what? A McDonalds?
If so, I'd say about every 12 min if it's on an interstate and every 25 min if on a state highway.
I know just between Space Center Houston and downtown, we passed like 6 of them. It was nuts!

Their 'head on' speed will be 52 + 60 = 112mph.
Their distance apart is 392 miles. So if we divide the total separation distance by the rate at which they are coming together we get:-
392 divided by 112 which equals 3.5 hours.
So the answer is 3 hours 30 minutes.

This is a simple algebra question. Did you learn the chart with V/R/T/D?
You need a variable x to equal the amount of hours and then write two equations to add up to the total distance.
The distance of Car 1 + distance of Car 2 = total distance.
To find distance multiply rate times time, since time is x, the distance of car 1 is 52x and the distance of Car 2 is 60x. Add them up. . .
52x + 60x = 392, now you solve for x

as the cars are moving towards each other in opposite directions, sum of thier speed * time = 392
so in that case, they will take 3 and half hours to pass each other
