As shown in the picture below, There is a circular car race track of 10km. There are two cars, we called them Car A and Car B. And they are at the exact opposite end to each other. At Time T(0), Both cars move toward each other at a constant speed of 100m / seconds. As we know both cars are at the same speed they will always be the exact opposite to each other.
