Boris and natasha start at the same place and at the same time on a 200 meter circular track and run in opposite directions. boris runs at 5 meters per second and natasha runs at 3 meters per seconds. in how many seconds will they first meet after starting?

If they run in opposite directions from the start, they are actually running towards each other on a circular track.

This means that the question is asking how long it takes to cover 200 meters if one person is running at 5 m/s and the other is running in the opposite direction at 3 m/s.

Since they are approaching each other at 8 m/s in total, the time taken to cover 200 meters is 200/8 = 25 seconds.
