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.
Note, at the center, there is a bug which starts flying towards Car A at time T(0). When the bug reaches car A, it turns back and starts moving towards the car B. The speed of bug is 1m/second. After 5hours all three stop moving.

18 km

Speed of bug - 1m/second
Time on fly- 5 hrs
Distance covered = 1m/second*5 hrs= 1m/second*5*3600 seconds= 18000 m= 18 km regardless trajectory
