As shown in the image below, there is a circular track of diameter of 5km. Two cars Car-A and CarB are at the exact diameter of the circular track.At time start say 'Ts', Both the cars moves clockwise at a constant speed of 90meter/seconds. Since both the cars move at a constant speed so at any time given say 'Ti', they will always be at opposite end of the diameter.
Note, at the center of the track there a bug which at the time 'Ti' starts moving towards Car-B and after reaching car-B moves back toward Car-A and after reaching car-A move towards Car-B and keeps repeating the entire cycle again and again. The speed of bug is constant at 2 meter/seconds. After 2 hours, both cars and bug stop.
What is the distance covered by the bug ?
