A and B run in opposite directions from P on a circle with different but constant speeds.

A runs in clockwise direction.

They meet for the first time at a distance of 900 meters in clockwise direction from P and

for the second time at a distance of 800 meters in anticlockwise direction from P.

If B is yet to complete one round, the circumference of circle is
